Abstract

Metal halide perovskites and their derivatives are gaining significant attention as photoluminescent materials due to their exceptional light-emitting properties. However, most research has concentrated on electroluminescence and photoluminescence, there remains a substantial gap in the exploration of mechanoluminescence (ML) properties in perovskites, making this field largely uncharted. ML is an ancient and intriguing luminescent phenomenon that occurs when a material is subjected to mechanical forces. Here, the discovery of the first organic–inorganic hybrid terbium (Tb3+)-based metal halide, a type of perovskite derivative, which exhibits notable ML properties is reported. Through material orthogonal design, the critical roles played by molecular geometry and metal-site ions in achieving remarkable ML in organic–inorganic hybrid metal halides are identified.

有机-无机金属卤化物钙钛矿衍生物的机械发光研究。
金属卤化物钙钛矿及其衍生物作为光致发光材料,由于其特殊的发光特性而受到广泛关注。然而,大多数研究都集中在电致发光和光致发光上,对钙钛矿机械致发光(ML)性质的探索仍然存在很大的空白,这使得这一领域在很大程度上是未知的。ML是一种古老而有趣的发光现象,当材料受到机械力时就会发生这种现象。本文报道了首个有机-无机杂化terbium (Tb3+)基金属卤化物的发现,这是一种钙钛矿衍生物,具有显著的ML特性。通过材料正交设计,确定了分子几何形状和金属位离子对实现有机-无机杂化金属卤化物的显著ML的关键作用。
