Lanthanide phosphors doped stimuli‐responsive fibres for advanced information encryption and anti‐counterfeiting: In both dark and bright situation

Abstract The increasing prevalence of flexible wearables underscores the urgent need for advanced anti‐counterfeiting technologies. However, photoluminescent anti‐counterfeiting fibre materials are currently plagued by inherent environmental light dependency flaws. Their fluoresc...

Robust Ferroelectricity in Chalcogenides Down to 2 nm Particles

ABSTRACT Nano‐ferroelectric materials are essential for advancing miniaturized energy converters, optoelectronics, and nonvolatile memory devices. However, the depolarizing fields of size‐reduced nanoparticles will weaken or even eliminate the ferroelectric spontaneous polarizati...
