摘　　要： 报道一种以氧化铟、盐酸和硫脲为原料，采用水热法制备纳米片和纳米颗粒自组装In2S2微米球的简易方法。采用扫描电镜（SEM）、X射线衍射仪（XRD）和透射电子显微镜（TEM）对产物进行表征。SEM结果表明；于140℃、恒温24h得到In2S2纳米片自组装微球，直径3～4μm，纳米片厚度约20nm，大小为0．5～0．8μm于160℃恒温24h得到In2S3纳米颗粒自组装微球，直径2．5～10μm，纳米颗粒大小为20～200nm。XRD结果表明制备的产物均为纯相立方晶相的In2S2；发光性能研究表明两种微球具有发冷光的性质。 A very simple template-free hydrothermal approach that reaction of In2O3with aqueous HCI and Thiourea to prepare hollow In2S3 micro-spheres was reported. The as-synthesized products were characterized by means of scanning electron microscopy,powder X-ray diffraction, transmission electron microscopy and photoluminescence. The results showed that the In2S3microspheres with the diameters of 3～4μm via the hydrothermal reaction 140℃ for 24 h are constructed from 2-dimensional In2S3 nano7 flakes with the cubic structure and the thickness of about 20 nm and with widths and lengths in the range of 0. 5～0. 8 μm. And the other InzS3 microspheres with the diameters of 2. 5～ 10μm via the hydrothermal reaction at 160℃for 24 h are constructed from InzS3nano-particle with the cubic structure and the size of 20～300 nm. The optical properties of In2S3 micro-spheres were also investigated.
