Organic-inorganic hybrid perovskites attract attentions because of their unique electro-optical properties which are expected to be applied to various devices. The perovskite compounds are generally prepared from precursor solutions consisting of two materials, AX and BX₂ for ABX₃. Generally, methylammonium lead triiodide (MAPbI₃) perovskite is formed from the precursor solution consisting of methylammonium iodide (MAI) and lead iodide (PbI₂). In this report, we select Pb(-S-C(S)-OR)₂ (lead xanthate, abbreviated as Pb(XT)₂) as the perovskite precursor instead of PbI₂. We found that the precursor solutions consisting of the MAI and the Pb(XT)₂ give nanocomposites consisting of MAPbI₃ and PbS nanomaterials including PbS quantum dot without changing the MAPbI₃ bandgap. In this report, nanocomposites prepared from precursors consisting of Pb(XT)₂/MAI with various ratios are analysed by using XRD, XPS, TG-DTA, TEM and UV/VIS spectroscopy.

有机-无机杂化钙钛矿因其独特的电光特性而备受关注，有望应用于各种器件。钙钛矿化合物通常由由两种材料组成的前体溶液制备，AX 和 BX ₂用于 ABX ₃。通常，甲铅三碘化物（MAPbI ₃）钙钛矿选自甲基铵碘化物（MAI）和碘化铅（PBI的前体溶液形成的₂）。在本报告中，我们选择 Pb(-SC(S)-OR) ₂（黄原酸铅，缩写为 Pb(XT) ₂）作为钙钛矿前体而不是 PbI ₂。我们发现由 MAI 和 Pb(XT) ₂组成的前体溶液给出由 MAPbI ₃和 PbS 纳米材料组成的纳米复合材料，包括 PbS 量子点，而不会改变 MAPbI ₃带隙。在本报告中，使用 XRD、XPS、TG-DTA、TEM 和 UV/VIS 光谱分析了由具有不同比例的 Pb(XT) ₂ /MAI组成的前体制备的纳米复合材料。
