However, they currently suffer from a short lifespan caused by a phase transition or water and oxygen erosion. Sustainably recycling end-of-life PSCs is essential for reducing environmental impact and saving costs on raw materials and time. Herein, we propose a “trash to treasure” economically recycling strategy, which utilizes ammonium salt-assisted octahedral [PbI6]4– reconstruction and rearrangement to in situ treat various degraded PSCs. X-ray detectors based on the recycled PSCs demonstrate significantly enhanced performances comparable to those of previously reported fresh PSCs. For example, the recycled FAPbI3 detectors show a high sensitivity of 4.32 × 104 μC Gyair–1 cm–2 and a low limit of detection of 8.3 nGyair s–1, along with a high spatial resolution of 7.0 lp mm–1. Furthermore, this method has also been successfully employed to construct 2D/3D heterojunctions. This method offers universality, effectiveness, and simplicity, thereby inspiring the recycling and reuse of degraded perovskites.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"91 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142841690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this comes at the cost of a complex readout that requires one coaxial cable for each pixel of the array. Here, we report a 28-pixel SNSPD with a dedicated parallel architecture that, while maintaining a simple readout with a single coaxial line, enables the detector to operate at high speed with low-performance degradation. The device shows a maximum single-photon efficiency of 88% and is able to maintain its efficiency above 50%, coupled with a timing jitter lower than 80 ps, up to a detection rate of 200 million counts per second.

The coexistence of solitons and an embedded dispersive wave background sets a challenge for characterizing and analyzing these transient dynamics. Here, we demonstrate the real-time full-field characterization of transient soliton dynamics in a mode-locked fiber laser using nonlinear Fourier transform (NFT) and high-bandwidth coherent homodyne detection, revealing new insights into the physics of optical soliton interactions within complex nonlinear systems. Such characterization includes the formation of multiple solitons amid wide relaxation oscillations, the switching of multiple solitons, and controlled soliton drifting with associated digital encoding. NFT proves its efficiency in separating and analyzing coherent structures among the dispersive wave radiation in fiber lasers. By implementation of the inverse NFT, the corresponding pure soliton distribution can be reconstructed.

The two reflection oscillation modes of the four pyramid optical cavities constructed within perovskite microcrystals promote photogenerated charge carriers’ attachment to the crystal side along the light reflection trajectory. The radial capacitance unique to the 3D heterojunction in this device guides the recombination of long wavelength charges gathered on the crystal surface, thus eliminating long-wavelength photoresponse to obtain an ultraviolet narrowband. As a result of the simultaneous narrowing of the response from both sides, a specific narrowband ultraviolet response with a full width at half-maximum (fwhm) of less than 40 nm is obtained. The synergistic effect of three regions in the dendritic microcrystals is used to capture photons and transport and confine charges, breaking through the limitation of the responsivity of a single microcrystalline unit to the same level of response as large-area polycrystalline devices.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"30 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While many schemes of dual-color IR detection are reported in the literature, there are few detectors which can independently address three or more colors and have drawbacks such as requiring postgrowth fabrication steps and significant crosstalk between colors. Here we demonstrate a contactless photoconductive IR detection architecture that overcomes these challenges and can detect and independently address multiple IR colors on a single busline by using different microwave frequencies. Our design couples photoconductive absorbers to the near-fields of unique modes in a single high permittivity (ε ∼ 80) dielectric microwave resonator driven by a continuous wave microwave source. Absorbed light in each photoconductor generates electron hole pairs, which correspondingly add losses to the specific resonator mode and increase the microwave signal transmitted at the respective resonant frequency. Each unique dielectric resonator mode interacts with a photoconductor of different bandgap enabling independent coverage and addressability at disparate wavelengths including near-infrared using silicon, short-wave infrared using germanium, and midwave infrared using mercury cadmium telluride. This detection architecture does not require complex growth methods, band offset engineering, optimized doping, mesa etches, or contact formation, opening the door to practical multicolor light detection across the spectrum.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"12 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stable pulsed TEM0,0 mode generation with a tunable pulse duration from 826.5 to 371.2 ns and a corresponding repetition rate from 63.7 to 121.3 kHz was achieved. Additionally, customizable transverse modes were generated from the Pr:YLF laser cavity using a noncollinear pumping technique to precisely manage the gain and loss characteristics of intracavity transverse modes. A first-order vortex beam at 640 nm was obtained through astigmatic mode conversion from the passively Q-switched Pr:YLF laser.

Devices based on quantum nanostructures remain non competitive due to unresolved drawbacks, the most significant being the need for cooling down to liquid nitrogen temperatures to improve the signal-to-noise ratio. In this work, we demonstrate an innovative solution to surpass the current generation of quantum dot-based detectors by exploiting absorption from quantum dot-localized states to resonant states in the continuum, that is, states in the semiconductor conduction band with an enhanced probability density in the quantum dot region. This unprecedented approach takes advantage of the unique properties of such states to massively enhance carrier extraction, overcoming one of the most crucial drawbacks of quantum dot-based infrared detectors. This innovative solution is discussed here from both theoretical and experimental perspectives. The measured room temperature operation demonstrates that exploiting resonant state absorption in quantum dots offers the long-sought solution for the next generation of infrared photodetectors.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"28 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142809368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the underlying mechanism of photoluminescence (PL) emission of AgNWs on a metal film (NWoF structure) is still under debate. Here, we provided an exhaustive investigation of the PL behaviors of AgNWs by performing substrate-dependent PL imaging, as well as power-dependent PL spectra and photoblinking dynamics of single AgNWs on an Ag film with Al2O3 as a dielectric space. The similar PL spectra among suspension AgNWs, crossed AgNWs on Si/SiO2 substrate, and single AgNWs on the Ag films confirmed that PL emission from NWoF structures is originated from AgNWs, rather than Ag films. Three PL peaks from AgNWs on the Ag film have been attributed to the photoactive Ag nanoclusters, the radiative recombination of intraband transitions, and the possible gap plasmonic modes, respectively, which have been evidenced by analysis of power-dependent PL spectra and photoblinking dynamics. These findings may provide new insight into the PL mechanisms of AgNWs and offer inspiration to develop customized plasmonic applications.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"16 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142809369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their low dimensionality also renders photoinduced dynamics and the resulting properties highly susceptible to defects. Yet, the mechanistic relationship between intrinsic defects and non-uniform optoelectronic responses has remained elusive, calling for spatially resolved characterization to visualize heterogeneous photoinduced dynamics. Here, we apply ultrafast infrared scattering scanning near-field optical microscopy (ultrafast IR s-SNOM) to investigate WS2 monolayers grown by chemical vapor deposition. We demonstrate that ultrafast IR s-SNOM, with the relatively high excitation fluence, sensitively probes the dynamics of electron–hole plasma induced in local domains of the individual WS2 monolayers. The transient mid-infrared response is enhanced with extended lifetimes near the edges, indicating local mitigation of many-body interactions. We propose that the spatially modulated many-body dynamics is associated with defect-mediated mechanisms, providing implications for engineering TMD-based nanoscale optoelectronics.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"1 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary criterion is that protons normally incident on a PSC during ground-based testing should create a uniform damage profile, mimicking the effect of the omnidirectional and polyenergetic proton spectrum in space orbit. However, given the low thicknesses of PSCs, proton energies >0.05 MeV can meet this criterion, leading to ambiguity regarding the precise energy needed for testing. Here, we highlight another major criterion: the optimal proton energy should also closely mimic the elemental vacancy distribution created in the perovskite by space protons. Using Monte Carlo ion-solid simulations, we first calculate the elemental vacancies in a PSC due to the low-Earth orbit (LEO) proton spectrum. We then show that only ∼0.07 MeV protons can result in a similar distribution during ground-based testing. Higher energies (∼1 MeV) lead to 25% more iodine, 33% more lead, and 50% fewer hydrogen vacancies, failing to represent the space radiation environment accurately. Our results offer precise guidelines for PSC radiation testing, paving the way for more accurate, reliable, and comparable assessments.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"228 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
