摘要

金属卤化物钙钛矿的动态无序是由交联八面体的热结构波动驱动的，导致电子拉曼散射谱低频区出现宽带中心峰。在这项工作中，实验证明了金属卤化物钙钛矿CsPbBr3的拉曼中心峰的温度依赖性。本研究结果为切削式远程温度传感器的发展提供了希望。

Electronic Raman Scattering Thermometry of Disordered Solids

Dynamic disorder in metal halide perovskites is driven by thermal structural fluctuations of cross-linked octahedra leading to a broadband central peak in the low-frequency region of electronic Raman scattering spectrum. In this work, a temperature dependence of the Raman central peak in metal halide perovskite CsPbBr₃ is experimentally demonstrated. The results of this study hold promise for the development of edge-cutting remote temperature sensors.
