Conventional anti-counterfeiting technologies based on low-dimensional metal halides are often constrained by complex and time-consuming heating and solvent treatments that may insufficiently modify the luminescent characteristics of emitters, thus hindering their practical implementation in effective anti-counterfeiting strategies. In this study, we employ an innovative alloying strategy in low-dimensional zinc halides Cs2ZnCl4 to enhance their luminescent performance. By introducing self-trapped exciton (STE) states through the alloying of Cu+ and Sb3+ ions in Cs2ZnCl4, we achieve bright blue and red photoluminescence (PL) centered at 492 nm and 744 nm, respectively, under 266 nm excitation, with only red emission observed under 365 nm excitation. This approach enables instant and reliable anti-counterfeiting applications. This work presents new opportunities for developing robust anti-counterfeiting and information encryption/decryption technologies.","PeriodicalId":19611,"journal":{"name":"Opto-Electronic Advances","volume":"8 10","pages":"250105-250105"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.oejournal.org/oea/en/article/pdf/preview/10.29026/oea.2025.250105.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147890375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a huge gap between the free-space vortices (FVs) and plasmonic vortices (PVs) on chips, and active manipulation as well as multiplexing in more channels have become a pressing demand. In this work, we demonstrate a terahertz (THz) cascaded metadevice composed of a helical plasmonic metasurface, a liquid crystal (LC) layer, and a helical dielectric metasurface. By spin-orbital angular momentum coupling and photon state superposition, PVs and FVs are generated with mode purity of over 85% on average. Due to the inversion asymmetric design of the helical metasurfaces, the parity symmetry breaking of OAM is realized (the topological charge numbers no longer occur in positive and negative pairs, but all are positive), generating 6 independent channels associated with the decoupled spin states and the near-/far- field positions. Moreover, by the LC integration, dynamic mode switching and energy distribution can be realized, finally obtaining up to 12 modes with a modulation ratio of above 70%. This active tuning and multi-channel multiplexing metadevice establishes a bridge connection between the PVs and FVs, exhibiting promising applications in THz communication, intelligent perception, and information processing.","PeriodicalId":19611,"journal":{"name":"Opto-Electronic Advances","volume":"8 5","pages":"240250-240250"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.oejournal.org/oea/en/article/pdf/preview/10.29026/oea.2025.240250.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147909184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, enormous attention has been paid to how to narrow their broadband spectra, ignoring the application advantages of the broadband emission. In this work, the AIGS QDs with controllable broad green-red dual-emission are first reported, which is achieved through adjusting the size distribution of QDs by controlling the nucleation and growth of AIGS crystals. Resultantly, the AIGS QDs exhibit broad dual-emission at green- and red- band evidenced by photoluminescence (PL) spectra, and the PL relative intensity and peak position can be finely adjusted. Furthermore, the dual-emission is the intrinsic characteristics from the difference in confinement effect of large particles and tiny particles confirmed by temperature-dependent PL spectra. Accordingly, the AIGS QDs (the size consists of 17 nm and 3.7 nm) with 530 nm and 630 nm emission could successfully be synthesized at 220 °C. By combining the blue light-emitting diode (LED) chips and dual-emission AIGS QDs, the constructed white light-emitting devices (WLEDs) exhibit a continuous and broad spectrum like natural sunlight with the Commission Internationale de l’Eclairage (CIE) chromaticity coordinates of (0.33, 0.31), a correlated color temperature (CCT) of 5425 K, color rendering index (CRI) of 90, and luminous efficacy of radiation (LER) of 129 lm/W, which indicates that the AIGS QDs have huge potential for lighting applications.","PeriodicalId":19611,"journal":{"name":"Opto-Electronic Advances","volume":"7 9","pages":"240050-240050"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.oejournal.org/oea/en/article/pdf/preview/10.29026/oea.2024.240050.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147885009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the emission of Sb3+ ions in OIHMHs is primarily confined to the low energy region, resulting in yellow or red emissions. To date, there are few reports about green emission of Sb3+-doped OIHMHs. Here, we present a novel approach for regulating the luminescence of Sb3+ ions in 0D C10H22N6InCl7·H2O via hydrogen bond network, in which water molecules act as agents for hydrogen bonding. Sb3+-doped C10H22N6InCl7·H2O shows a broadband green emission peaking at 540 nm and a high photoluminescence quantum yield (PLQY) of 80%. It is found that the intense green emission stems from the radiative recombination of the self-trapped excitons (STEs). Upon removal of water molecules with heat, C10H22N6In1-<italic>x</italic>Sb<italic>x</italic>Cl7 generates yellow emission, attributed to the breaking of the hydrogen bond network and large structural distortions of excited state. Once water molecules are adsorbed by C10H22N6In1-<italic>x</italic>Sb<italic>x</italic>Cl7, it can subsequently emit green light. This water-induced reversible emission switching is successfully used for optical security and information encryption. Our findings expand the understanding of how the local coordination structure influences the photophysical mechanism in Sb3+-doped metal halides and provide a novel method to control the STEs emission.","PeriodicalId":19611,"journal":{"name":"Opto-Electronic Advances","volume":"7 3","pages":"230197-230197"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.oejournal.org/data/article/export-pdf?id=65f0feaf99d881433ef827db","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147896010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Addressing these challenges, we present a novel near-infrared (NIR)-triggered RNS nanoreactor (PBNO-Ce6) to amplify the photodynamic and photothermal therapy efficacy against triple-negative breast cancer (TNBC). The designed PBNO-Ce6 combines sodium nitroprusside-doped Prussian Blue nanoparticles with Chlorin e6 to enable on-site RNS production through NIR-induced concurrent NO release and ROS generation. This not only enhances tumor cell eradication but also potentiates local and systemic antitumor immune responses, protecting mice from tumor rechallenge. Our in vivo evaluations revealed that treatment with PBNO-Ce6 leads to a remarkable 2.7-fold increase in cytotoxic T lymphocytes and a 62% decrease in regulatory T cells in comparison to the control PB-Ce6 (Prussian Blue nanoparticles loaded with Chlorin e6), marking a substantial improvement over traditional PTT/PDT.

Current data-driven deep learning algorithms face the challenge that the labeled training datasets limit the training performance and generalization. The model-driven deep learning introduces the diffraction model into the neural network. It eliminates the need for the labeled training dataset and has been extensively applied to hologram generation. However, the existing model-driven deep learning algorithms face the problem of insufficient constraints. In this study, we propose a model-driven neural network capable of high-fidelity 4K computer-generated hologram generation, called 4K Diffraction Model-driven Network (4K-DMDNet). The constraint of the reconstructed images in the frequency domain is strengthened. And a network structure that combines the residual method and sub-pixel convolution method is built, which effectively enhances the fitting ability of the network for inverse problems. The generalization of the 4K-DMDNet is demonstrated with binary, grayscale and 3D images. High-quality full-color optical reconstructions of the 4K holograms have been achieved at the wavelengths of 450 nm, 520 nm, and 638 nm.","PeriodicalId":19611,"journal":{"name":"Opto-Electronic Advances","volume":"1 1","pages":""},"PeriodicalIF":14.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69522178","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}
