Abstract

We introduce a strategy to develop multiple-phase structure of inorganic lead halide perovskite CsPbBr₃. The method is based on local optical heating, which allows the creation of strong temperature gradients. Using Raman spectroscopy, it was determined that such gradients induce a distribution of phase transitions within the perovskite crystal. We show that such gradients lead to perovskite multiple-phase structure.

相梯度 CsPbBr3 包晶结构

摘要我们介绍了一种开发无机卤化铅包晶 CsPbBr3 多相结构的策略。该方法以局部光学加热为基础，可以产生很强的温度梯度。利用拉曼光谱，可以确定这种梯度会诱发包晶内部的相变分布。我们的研究表明，这种梯度导致了包晶的多相结构。
