Summary: This study demonstrates a promising and simple strategy using silver nanowires (NWs) embedded in UV-curable epoxy to achieve mechanically robust and ITO-free flexible organic photovoltaics (OPVs). The resulting resin-embedded ZnO-encapsulated silver nanowire (REZEN) electrode exhibits highly planar surfaces and excellent mechanical stability. OPV cells based on the REZEN electrode show comparable performance with reference devices and retain high efficiency even after multiple cycles, making them highly flexible and durable.

Summary: Persistent luminescence is a unique visual phenomenon where luminescence continues even after excitation light has stopped or the luminescent molecules have oxidized. Organic persistent luminescence materials (OPLMs) are highly durable and can be easily modified and assembled into biocompatible nanostructures, making them attractive for in vivo bioimaging applications. This review discusses the limitations of each class of OPLM-based molecular bioimaging probes based on their luminescence mechanisms, and explores recent research progress and potential biological applications. Insights into the next generation of OPLMs for bioimaging techniques are also provided.

Summary: A facile strategy was developed to prepare color-controllable room-temperature phosphorescence (RTP) materials through the pyrolysis of a mixture containing 1-(2-hydroxyethyl)urea and boric acid. By controlling the pyrolysis temperatures, the resulting materials exhibited ultralong RTP with tunable emission colors. The study also revealed the formation of multiple luminescent centers, in-situ embedded in the B2O3 matrix, by the pyrolysis process, allowing for color-tunable RTP.

Summary: Lead halide perovskite nanocrystals with a perovskite/linear low-density polyethylene (perovskite/LLDPE) core/shell structure were successfully synthesized to achieve high photoluminescence quantum yield (PLQY) and high stability. The improved photoluminescence properties were attributed to the enhanced pressure effect and interaction between ligand and perovskite crystals. The resulting nanocrystals showed high stability under ambient conditions and against UV light, and were used to fabricate white-emitting Mini-LEDs with a super wide color gamut.

Summary: This study reports the electron tunneling charging behavior in Cr3+, Sm3+ co-doped near-infrared persistent luminescence material SrGa12O19, allowing for efficient charging by incoherent visible light. The electrons are efficiently captured by nearby Ga-II-O2- electron-hole trap centers via a tunneling process and transferred to shallow traps through a persistently energetic optical pump. The PersL performance is further optimized by engineering the energy band through partial substitution of In3+ for Ga3+. Insights into electron tunneling charging under low-energy excitation for near-infrared persistent luminescence are provided, inspiring more explorations for practical applications.

Summary: This study presents a laser-driven white light source with high brightness and excellent color rendition, achieved by designing CaAlSiN3:Eu@Al (CASN@Al) converters that tightly bond all-inorganic phosphor films on an aluminum substrate.
