Bismuth and antimony were reacted in sulfur/iodine flux mixtures at various temperatures and iodine concentrations to explore the effects of these variables on the synthesis and properties of BiSbSI products. The products grow as crystals; microprobe elemental analysis and UV/vis/NIR spectroscopy of the BiSbSI solid solutions indicate that substitution is homogeneous within individual crystals but varies up to 15% between crystals within each synthesis batch. Raman spectra show a two-mode behavior upon substitution, indicating covalent bonding within the structure, and TEM/SEM data confirm no presence of nanoclustering or segregation within the crystals.
铋和锑在不同温度和碘浓度的硫/碘助熔剂混合物中发生反应，以探究这些变量对BiSbSI产物的合成及性质的影响。产物以晶体形式生长；对BiSbSI固溶体进行的微探针元素分析和紫外/可见/近红外光谱表明，单个晶体内的取代是均匀的，但在每个合成批次的晶体之间，取代变化高达15%。拉曼光谱显示取代时呈现双模行为，表明结构内存在共价键，透射电子显微镜/扫描电子显微镜数据证实晶体内不存在纳米团聚或偏析现象。
