Abstract

In recent years, due to the toxicity and instability of halide lead-based perovskites, the search for alternatives that retain the superior optoelectronic performance of halide lead-based perovskite materials while being non-toxic and stable has gradually become an important research topic. Among them, the lead-free perovskites with the general formula A₄M^IIM^III₂X₁₂ are very promising in solving the problem of lead ion toxicity. Here, we have studied the Cs₄CuSb₂Cl₁₂ perovskite material, which is a three-layer (n = 3) perovskite structure oriented along <111>. In this paper, a series of Cs₄Cu_1-xCd_xSb₂Cl₁₂ (0 ≤ x ≤ 1) and Cs₄Cu_1-yMn_ySb₂Cl₁₂ (0 ≤ y ≤ 1) microcrystals were synthesized. By varying the value of x and y, we successfully tuned the bandgap and optical properties of Cs₄CuSb₂Cl₁₂. This allowed us to establish a clear correlation between the material's composition, structure, and properties, laying the foundation for further research and application of Cs₄CuSb₂Cl₁₂ materials.

无铅层状双钙钛矿的组成、结构和性能的调整

近年来，由于卤化物铅基钙钛矿的毒性和不稳定性，寻找既保留卤化物铅基钙钛矿材料优越的光电性能，又无毒稳定的替代品逐渐成为一个重要的研究课题。其中，通式为A4MIIMIII2X12的无铅钙钛矿在解决铅离子毒性问题上非常有前景。在这里，我们研究了Cs4CuSb2Cl12钙钛矿材料，它是一种沿<；111>；取向的三层（n = 3）钙钛矿结构。本文合成了一系列Cs4Cu1-xCdxSb2Cl12（0≤x≤1）和Cs4Cu1-yMnySb2Cl12（0≤y≤1）微晶。通过改变x和y的值，我们成功地调整了Cs4CuSb2Cl12的带隙和光学性质。这使我们建立了材料的组成、结构和性能之间的清晰相关性，为Cs4CuSb2Cl12材料的进一步研究和应用奠定了基础。
