Abstract

Pressure-Induced Unusual Transition of Luminescence Mechanics

In article number 2402086, Lingrui Wang, Junnian Chen, Lei Zhang, Haizhong Guo, and co-workers report that (C₆H₁₀N₂)PbBr₄ and (C₆H₁₀N₂)PbCl₄ exhibit excitation-dependent emission enhancement under excitation at 303 nm and 355 nm, highlighting a piezochromic luminescence property. This phenomenon is attributed to lattice compression, which reduces the electron-phonon coupling strength. This work not only offers effective methods to modulate the optical properties of hybrid perovskites but also opens avenues for further exploration of their novel photophysical properties.
