A study has been performed by investigating the variation of absorbance and photoluminescence intensity of the perovskite as a function of precursor mixing ratios at room temperature. In this study we used CH₃NH₃SnCl₃ perovskite wherein CH₃NH₃Cl and SnCl₂ solutions are the precursors. These two precursors are mixed with ratios of 3:1, 1:1 and 1:3. XRD, UV–Vis absorption and photoluminescence studies were carried out in both solution and film form.

前驱体混合比对甲基钙氯化锡铵钙钛矿的光学和结构性能的影响

通过研究钙钛矿的吸光度和光致发光强度随室温下前驱体混合比的变化而进行的研究。在这项研究中，我们使用了CH ₃ NH ₃ SnCl ₃钙钛矿，其中CH ₃ NH ₃ Cl和SnCl ₂溶液是前体。将这两种前体以3：1、1：1和1：3的比例混合。XRD，UV-Vis吸收和光致发光研究均以溶液形式和薄膜形式进行。
