Among the materials explored for constructing these devices, 2D transition metal oxides (TMOs) stand out due to their tunable compositions, exceptional stability, and unique optoelectronic properties. However, challenges such as complex device architectures, compromised material quality, and high energy consumption persist. Herein, the successful growth of 2D nonlayered α-Fe2O3 nanoflakes is reported via a molecular sieve-assisted chemical vapor deposition (CVD) method. These nanoflakes, with a minimum thickness of two unit cells, exhibit high crystallinity, n-type charge carrier transport properties, and response to 450 nm laser illumination. Notably, the charge trapping/de-trapping at oxygen vacancies (VO) and the light-induced ionization of VO contribute to the distinct electron concentration and current hysteresis during cyclic voltage sweeps in the thin α-Fe2O3 nanoflakes. This mechanism results in a significantly prolonged photocurrent decay, enabling the emulation of biological synaptic behaviors such as excitatory postsynaptic current (EPSC), paired-pulse facilitation (PPF), short-term potentiation (STP), and long-term potentiation (LTP). Combined with the scalability of the CVD process, this work highlights the potential of 2D α-Fe2O3 for applications in integrated artificial vision systems.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 14","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, spintronics relies on external magnetic fields and ferromagnetic contacts to achieve spin-polarized carriers. This makes it challenging to realize flexible spin devices due to the inherently bulky and rigid constituent materials. To overcome these drawbacks, a strategy is proposed for fabricating flexible spin light-emitting diodes by integrating self-assembled monolayer (SAM) of P3HT-COOH, chiral metal–organic framework (Chiral-MOF), quantum dots (QDs), and polyethylene terephthalate substrate. The chiral europium-based MOFs employed as a spin-injection layer via the chiral-induced spin selectivity mechanism can effectively polarize the emitting light. The SAM (P3HT-COOH) layer significantly enhances the device stability and light intensity compared to conventional PEDOT: PSS layer-based devices, while the QDs layer serves as the bright emitter. This device achieves an estimated external quantum efficiency (EQE) with a polarization degree (PCP-EL) of ± 21.86%. Furthermore, PCP-EL changes (21.86, 20.34, 19.34, 17.45, 17.18, 14.99, 13.54) with stable emission under various bending radii. This approach enables circularly polarized luminescence (CPL) and a tuneable degree of polarization simultaneously, which is free from external magnetic fields or ferromagnetic contacts. The obtained result offers a promising alternative in the field of flexible spintronics and builds up an additional manner to manipulate the physical properties of spin devices.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 15","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, synergizing interlayer and intralayer coupling in heterostructures has achieved significant modulation of light-matter interaction through tailored band alignment, offering potential solution to obstacles faced by MoS2. Utilizing the high work function characteristics of CrOCl, a synergistic and bridgeable charge transfer engineering is reported to 1L MoS2, with facilitated electron migration and abnormal PL enhancement in wedding-cake-like MoS2/CrOCl heterostructures. Energy band calculations and surface potential characterizations reveal that the observed 26.5-fold PL enhancement is ascribed to the band offset in 1L MoS2. Strong coupling at CrOCl interface opens an extra in-plane electron migration channel from 1L MoS2 to multilayer-MoS2, driving the abnormal enhancement. As an intuitive perception of in-plane charge transfer process, Au bridge is designed as conductive channel within MoS2/CrOCl heterostructures, enabling desirable PL transition effect in 1L MoS2 from “off state” to “on state”. Such PL transition proves that synergistic in-plane charge transfer is effectively bridgeable, transcending covalent bond limitations. These results enhance the understanding of the synergistic charge transfer mechanism in heterostructures and develop novel high-efficiency MoS2-based optoelectronic devices.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 14","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As it occurs in all the kingdoms of life, photochromic compounds play a relevant role. Several living beings exploit photochromic switches for variegate responses to the features of the environmental light. This work proposes a plausible justification by evidencing how each photochrome can be conceived as a trivial form of Markov blanket and implement (i) forward, (ii) final, and (iii) circular causalities. Furthermore, photochromic materials are appropriate for processing Boolean and fuzzy logic, exploiting their chemical reactivity, chaos, and quantum computing. Finally, photochromic molecules and oscillatory chemical reactions are promising ingredients for developing neuromorphic engineering in wetware based on optical signals.

In 2015, Park and colleagues demonstrated the first perovskite-based single-photon source operating at room temperature (RT) using all-inorganic CsPbI3 quantum dots (QDs). Since then, quantum light emission has been observed in various perovskite nanocrystals (PNCs) at both RT and cryogenic temperatures. Despite the remarkable features of PNCs, the use of PNCs for the incoming quantum technologies with light is restricted by their photostability and their challenging integration into photonics platforms. In this study, cryogenic µ-photoluminescence (µ-PL) is utilized, and µ-Time-Resolved Photoluminescence (µ- TRPL) spectroscopy to investigate the spectral stability of single colloidal cesium lead halide PNCs with different capping ligands. Notably, it is found that using a Zwitterionic (ZW) ligand significantly reduces the blinking effect and spectral diffusion for the cesium lead bromide PNCs, enhancing their spectral stability and reducing their µ-PL linewidths (≈125–140 µeV). Additionally, a slightly longer decay time (by a factor of ≈1.35) is observed in single cesium lead bromide PNCs capped with this ZW ligand, indicating a reduction in undesirable effects such as Auger recombination. These findings can pave the way for utilizing perovskites based single photon sources as key components in quantum technology-oriented applications.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 14","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key enabler of this work is ion beam processing at an angle sufficiently off-normal incidence, inducing self-assembly of a deposited metal layer into quasi-linear metallic features that can function as an etching mask. As a result, a fused silica metasurface, monolithic to the underlying substrate, is demonstrated at 375 nm wavelength to exhibit a phase delay angle of 30° between the principal axes. The capability of an angled etch mask replenishment process is also demonstrated for achieving deeper etch depth and for increasing the grating period, another first – to the best of the knowledge. This is the first display of a technology capable of fabricating glass-engraved near-linear grating structure with a feature-to-feature period as small as 118.6 nm. Furthermore, this technology has the potential to generate grating-like structures with periods as small as 12.4 nm, as demonstrated here with reactive ion beam processing assisted mask assembly. These structures are shown to have reflectivity < 0.4% across the wavelength band 350 nm – 1000 nm.
