摘要

全无机卤化物包晶 CsPbX3（X=Cl、Br、I）在光电器件方面显示出令人鼓舞的潜力。本研究采用三种不同的溶剂，即二甲基甲酰胺（DMF）、二甲基亚砜（DMSO）以及二甲基亚砜和二甲基甲酰胺的混合物，通过简单的方法合成了 CsPbCl3 包晶体。通过比较 CsPbCl3 包晶石的结构、光学和电学特性，确定了合成过程中的最佳溶剂。与其他两种氯化锑包晶相比，二甲基亚砜基氯化锑包晶的光带隙值为 2.96 eV，同时还具有高光致发光强度、高电荷载流子迁移率（29.8 cm2/V-s）和低电阻率（8.06 x 107 Ω-cm）。这些结果表明，DMSO 溶剂在实现适用于光电器件的 CsPbCl3 包晶石所需的光学和电学特性方面发挥着重要作用。

Optimizing the properties of CsPbCl3 perovskites using a solvent-based synthesis approach

All-inorganic halide perovskites CsPbX₃ (X = Cl, Br, I) have shown encouraging potential for optoelectronic devices. In this work, the synthesis of CsPbCl₃ perovskites is reported by a simple approach using three different solvents namely dimethylformamide (DMF), dimethyl sulfoxide (DMSO) and a mixture of dimethyl sulfoxide and dimethylformamide. The structural, optical and electrical properties of CsPbCl₃ perovskites are compared to identify the optimal solvent for the synthesis process. The DMSO-based CsPbCl₃ perovskite exhibits an optical bandgap value of 2.96 eV along with high photoluminescence intensity, high charge carrier mobility (29.8 cm²/V-s), and low resistivity (8.06 x 10⁷ Ω-cm) compared to the other two CsPbCl₃ perovskites. These results indicate that DMSO solvent plays an important role in achieving desired optical and electrical properties of CsPbCl₃ perovskites suitable for optoelectronic devices.
