Synthesis and characterization of various classical indium xanthate complexes of the type [InCl(3-n)(S2COR)n] (n = 1, 2, or 3; R = Me, Et, Pr(i), and Bu(s)) have been discussed. Crystalline beta-ln2S3 nanoparticles were obtained by the solvent thermolysis of indium tris-alkylxanthates in ethylene glycol at 196 degrees C, and were characterized by elemental analysis, IR, powder XRD, and XPS techniques. TEM results showed that the size of beta-In2S3 nanoparticles depended on the nature of the precursor used. The optical properties of beta-In2S3 nanocrystals have shown quantum confinement of the excitonic transition.
已对各种类型为[InCl(3 - n)(S2COR)n](n = 1、2或3;R = 甲基、乙基、异丙基和叔丁基)的经典铟黄原酸盐配合物进行了合成与表征。通过在196℃下于乙二醇中对三烷基黄原酸铟进行溶剂热解获得了结晶β - In2S3纳米颗粒,并采用元素分析、红外光谱、粉末X射线衍射和X射线光电子能谱技术对其进行了表征。透射电子显微镜结果表明,β - In2S3纳米颗粒的尺寸取决于所使用前驱体的性质。β - In2S3纳米晶体的光学性质显示出激子跃迁的量子限域效应。
