The synthesis of the complete range of (Bi Sb )S solid solutions, where 0 ≤ ≤ 1, by the variation of the mole ratio of bismuth and antimony piperidine dithiocarbamate complexes is reported. There was a near linear expansion of and lattice parameters as the mole ratio of the antimony precursor was increased. The composition of the particles directionally followed the amount of precursor ratio used. When the composition of particles was compared to cell parameters, a slight deviation from Vegard's law was observed with a corresponding contraction of the parameter and an approximately 3.5% reduction of the lattice volume. The nanorods obtained showed aspect ratios that depend on the composition of the material. The Bi and Sb rich materials had high aspect ratios of 16.58 and 16.58 respectively with a minimum aspect ratio of 2.58 observed for = 0.50.
据报道，通过改变铋和锑的哌啶二硫代氨基甲酸盐配合物的摩尔比，可以合成0≤≤1范围内的完整系列（Bi Sb ）S固溶体。随着锑前驱体摩尔比的增加，和晶格参数几乎呈线性膨胀。颗粒的组成定向地遵循所用前驱体比例的量。当将颗粒组成与晶胞参数进行比较时，观察到与维加德定律略有偏差，参数相应收缩，晶格体积减少约3.5%。所获得的纳米棒的长径比取决于材料的组成。富含铋和锑的材料分别具有16.58和16.58的高长径比，对于 = 0.50观察到的最小长径比为2.58。
