Here, we demonstrate visible-light-only photoprogramming of organic field-effect transistors (OFETs) by integrating an all-organic triplet-sensitized diarylethene system into the channel layer. Rather than redesigning the photoswitch, this modular additive strategy renders a conventional UV-responsive diarylethene visible-addressable in solid-state transistors. A ternary blend of a polymer semiconductor (DPP-DTT), a diarylethene photoswitch (DAE-HP), and an organic triplet sensitizer (4CzIPN) enables fully reversible current modulation via photocyclization at 450 nm and photocycloreversion at 520 nm. The devices achieve a switching ratio up to 2.8 × 10³ and remain stable over 100 cycles. Mechanistic studies show that DAE-HP and 4CzIPN co-localize within amorphous domains without perturbing polymer crystallinity, maintaining charge-transport continuity while ensuring the short-range proximity required for triplet exchange. Transient absorption spectroscopy supports efficient triplet–triplet energy transfer (TTET) from 4CzIPN to DAE-HP as the driver of visible-light photoswitching. These results identify nanoscale organization as the key lever for UV-free operation and provide a practical blueprint for safer, durable, and solution-processable light-programmable organic electronics.</p>","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"14 13","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202503525","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among various strategies, photoelectric devices that convert light into localized electrical signals have emerged as promising platforms for wireless, noninvasive, and nongenetic modulation of biological functions. Silicon (Si) has attracted particular interest as a biointerface material due to its high stimulation efficiency, biocompatibility, controllable biodegradability, and compatibility with flexible device architectures. This review provides a comprehensive overview of flexible Si-based photoelectric systems, including recent advances in material design and fabrication, as well as the fundamental mechanisms governing device/tissue interactions, with an emphasis on interfacial electrical processes that regulate biological responses. Representative biomedical applications are highlighted, spanning cardiac pacing, brain neural excitation, wound healing, nerve repair, and myocardial protection. Finally, key challenges, such as long-term biocompatibility, device stability, and spatiotemporal control of stimulation, are critically assessed, and future directions are outlined toward multimodal, adaptive, and integrated therapeutic systems. By establishing a materials-to-application framework, this review provides guidance for the rational design and biomedical translation of Si-based photoelectric biointerfaces and underscores their transformative potential in next-generation regenerative therapies.</p>\u0000 </div>","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"14 13","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683785","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}

So far, polaritonic crystals have been demonstrated within the Type-II Reststrahlen band (RB-II) where the in-plane components of the dielectric permittivity tensor are negative, while the out-of-plane component is positive. By contrast, a Type-I Reststrahlen band (RB-I) is characterized by the negative out-of-plane and positive in-plane permittivity, and consequently, the inversion of PhP field symmetry, negative phase velocity, and anomalous dispersion. Such an operation regime remains unexplored for periodic structures supporting collective polaritonic modes. Here, we employ a biaxial crystal α-MoO₃ and near-field imaging to study mid-infrared polaritonic Bloch modes in a 1-D Fourier crystal within the RB-I. Surprisingly, we observe a manifestation of Bloch waves as a dispersionless near-field pattern across the first Brillouin zone, in contrast to previous works exclusively focused on the RB-II.

However, Tm³⁺ still exhibits weak emission in double perovskites (DPs) owing to the parity-forbidden nature of its f–f transitions, leading to poor absorption. In this study, the rare-earth-based DP Cs₂NaTmCl₆ was successfully synthesized via a facile method. This material exhibits self-sensitized NIR-I and NIR-II emission under its characteristic excitation. Upon introducing Sb³⁺ ions, which possess strong absorption in the UV region, the NIR photoluminescence external quantum efficiency (EQE) of Cs₂NaTmCl₆:3% Sb³⁺ reaches 21.6%. This enhancement is attributed to the presence of the ¹G₄ energy level of Tm³⁺, which acts as a bridge to efficiently transfer energy from the high-energy states of Sb³⁺ to the NIR-emitting states of Tm³⁺. Both the pristine and Sb³⁺-doped Cs₂NaTmCl₆ demonstrate excellent thermal quenching resistance. Through a combined experimental and theoretical approach, we demonstrate that the incorporation of Sb³⁺ ions reduces the effective optical bandgap of the host matrix by providing additional absorption channels. Leveraging the efficient NIR luminescence, we designed an NIR night-vision illumination and imaging system. Furthermore, exploiting the emergence of visible luminescence and the distinct NIR emission intensities before and after Sb³⁺ doping, we developed a dual-mode optical anti-counterfeiting label.

To mitigate such intrinsic halide ion mobility in 3D perovskites, lower-dimensional (2D) perovskites are employed as barriers to stabilize the perovskite layers. Interestingly, 2D halide perovskites also exhibit halide ion mobility that is dependent on the binding configuration, viz., Ruddlesden–Popper (RP) and Dion–Jacobson (DJ) phases.
