Abstract

Copper-based halide perovskites are evolving as alternative materials to lead-based perovskites. Herein, we report the synthesis of double organic cation copper-halide perovskites (C₄H₉NH₃)_x(3-BrC₃H₆NH₃)_2–xCuCl₂_+xBr_2–x (x = 0.7, 1.0, 1.3, 1.6, and 1.9). The crystal structures were studied by powder X-ray diffraction (XRD). The optical properties of the perovskite thin films were investigated by UV–vis absorption spectroscopy and spectroscopic ellipsometry. It was demonstrated that the use of multiple cations is an effective compositional strategy to control the structural properties of two-dimensional (2D) perovskites. In addition, the thermochromism was also investigated by differential scanning calorimetry and in situ temperature-dependent powder XRD. This topic opens up a path for 2D copper-based halide perovskites to adjust their optical properties via spacer cation engineering. This research inspires future research interests in designing environmentally friendly 2D metal halide perovskites.

含混合有机阳离子的二维铜基卤化物包光体的可调谐光学特性

铜基卤化物过氧化物正逐渐成为铅基过氧化物的替代材料。在此，我们报告了双有机阳离子卤化铜包荧光体 (C4H9NH3)x(3-BrC3H6NH3)2-xCuCl2+xBr2-x （x = 0.7、1.0、1.3、1.6 和 1.9）的合成。通过粉末 X 射线衍射 (XRD) 对晶体结构进行了研究。紫外可见吸收光谱和光谱椭偏仪研究了过氧化物薄膜的光学特性。研究表明，使用多种阳离子是控制二维（2D）包晶石结构特性的有效组成策略。此外，还通过差示扫描量热法和原位温度依赖性粉末 XRD 研究了热致变色。该课题为二维铜基卤化物包晶通过间隔阳离子工程调整其光学性质开辟了一条道路。这项研究激发了未来设计环境友好型二维金属卤化物包晶石的研究兴趣。
