This issue impedes practical device applications of shortwave infrared Er-doped phosphors. Herein, with the mediation of surface vibrational phonons, anti-thermal quenching of Er3+ 1540 nm emission is reported in (220)-dominated Er3+-doped Cs2NaHoCl6 double perovskite. The downshifting emissions can be boosted with rising temperatures from 303 to 543 K, reaching 225%@483 K of the initial intensity at 303 K, accompanied with a long lifetime of 33.02 ms at 483 K. By combining temperature-dependent in situ Raman and Fourier transform infrared spectroscopies with the excited-state dynamics results, the coordination role of water molecules is verified, serving as promoters instead of quenchers on the (220) facet at high temperatures. Furthermore, efficient energy transfer from Ho3+ to Er3+ enables intense 1540 nm emission with a photoluminescence quantum yield of 78.1% under 450 nm excitation. Finally, a compact thermally stable phosphor-converted light-emitting diode (LED) is designed as a narrowband shortwave infrared light source with a blue LED chip. This work pushes the improved understanding of achieving thermal-enhanced Er3+ luminescence for potential broad applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":null,"pages":null},"PeriodicalIF":11.0,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142159009","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}

In this work, different from the traditional hollow‐core fibers and multiple thin solid plates, the generation of an octave‐spanning supercontinuum broadening is demonstrated by utilizing multiple ultrathin liquid films (MTLFs) as the nonlinear media. The continuum covers a range from 380 to 1050 nm, corresponding to a Fourier transform limit pulse width of 2.5 fs when 35 fs Ti: sapphire laser pulse is applied on the MTLFs. The output pulses are compressed to 3.9 fs by employing chirped mirrors. Furthermore, a continuous high‐order harmonic spectrum up to the 33rd order is realized by subjecting the compressed laser pulses to interact with Kr gas. The utilization of flowing liquid films eliminates permanent optical damage and enables wider and stronger spectrum broadening. Therefore, this MTLFs scheme provides new solutions for the generation of highly efficient supercontinuum and nonlinear pulse compression, with potential applications in the fields of strong‐field physics and attosecond science.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":null,"pages":null},"PeriodicalIF":11.0,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142144393","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}

Here, the origin of terahertz generation from a metal wire is revisited and a comprehensive diagnosis of the terahertz radiation from a 100 µm-diameter tungsten wire irradiated by an intense femtosecond laser is implemented. For the first time, the long-neglected but more efficient high-frequency terahertz radiation is experimentally observed of which the spectra, polarization, tunability, and wire-length-dependent intensification are investigated comprehensively. A new picture of the wire radiation dynamics is presented to reveal the origin of the extreme terahertz surface wave, its evolution, and radiation mechanism. This extremely intense and ultrashort half-cycle surface wave is spontaneously induced by a laser-driven transient charge-separation field and evolves into a multi-cycle surface wakefield structure as it propagates along the wire owing to the self-interaction between the surface wave and its carrier, the surface current. By manipulating the coupling and transport dynamics of the surface wave on the wire, tunable and intensified THz radiation covering a wide range from 0.1 to 20 THz has been realized, paving the way for broad applications such as terahertz acceleration, bio-medicine, nonlinear THz science and beyond.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":null,"pages":null},"PeriodicalIF":11.0,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142142860","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 device applications are hampered by light‐induced ion migration and halide segregation, leading to the formation of lower bandgap domains with red‐shifted photoluminescence. Previous studies of phase segregation in MHPs have predominantly focused on their linear optical properties. Herein, nonlinear absorption (NLA) properties of MAPbBr2I films before and after femtosecond laser irradiation are investigated using the Micro‐I‐scan technique. An unusual NLA switching from reverse‐saturable absorption (RSA) to saturable absorption (SA) under intense laser illumination is found. It is unveiled that the initial RSA originates from two‐photon absorption in uniform bromide‐rich regions of as‐prepared film whereas the SA occurs due to state filling effect in the newly generated low bandgap I‐rich phases under laser irradiation. The switching threshold and effective NLA coefficient are highly dependent on the distribution of halide ions, which is controllable through the laser illumination time. Furthermore, an all‐optical logic gate scheme is demonstrated based on the unusual NLA switching. The results not only unveil that halide segregation results in NLA switching in MHPs but also pave the way for the realization of MHPs‐based nonlinear photonic devices.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":null,"pages":null},"PeriodicalIF":11.0,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142142378","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}

In this study, experimental demonstrations are conducted to showcase how metasurfaces can enable the control of symmetry‐broken and Friedrich–Wintgen BICs by leveraging the asymmetry of split resonant rings. This approach allows for the existence of multiple free‐control BIC resonances and tailored enhancement of controlling light–matter interactions. Further experiments are conducted to validate the effectiveness and performance of meta‐sensors for the identification of the distinct fingerprint of α‐lactose with high sensitivity using only one single metasurface.

In this study, copper(I) iodide and benzotriazole derivative ligands with diverse cationic substituents are employed to fabricate all‐in‐one (AIO) colloidal copper(I) iodide cluster‐based scintillator suspensions. These suspensions, characterized by distinctive ionic and coordination bonds, are synthesized via confined growth in the presence of polyvinylpyrrolidone (PVP). Furthermore, they demonstrate exceptional compatibility with polymer matrices, facilitating the production of uniform and flexible scintillation films with highly efficient radioluminescence through blade coating. The resulting films achieved an excellent spatial resolution of 17 lp mm−1.

Here, an all‐inorganic metal halide RbCdCl3, featuring a reversible structural phase transformation from non‐perovskite (orthorhombic‐phase) to perovskite (tetragonal‐phase) structure is reported. Intriguingly, via phase transformation regulation engineering, a near‐unity photoluminescence quantum yield (PLQY) along with large Stokes shift (275 nm) and long decay lifetime (14.69 ms) is achieved in RbCdCl3:Mn2+ thermochromic fluorescent materials, comparing with the pristine non‐pervoskite structure with an initial PLQY of 3.1%. Moreover, the underlying PL switching mechanisms are systematically elucidated by the in situ optical characterizations and the first‐principles calculations.
