| 摘要: 以五水四氯化锡和三氯化锑为主要原料，以乙二醇为溶剂，采用溶剂热法合成了锑掺杂氧化锡(ATO)纳米球。用X射线衍射仪和透射电子显微镜对合成的ATO纳米球进行结构表征，用紫外可见分光光度计和低阻抗表面阻抗仪研究其光电性能。结果表明：所合成的ATO均为四方晶型结构，由粒径为5~10 nm的ATO纳米晶聚集成直径为80~120 nm的纳米球，且分散性良好。Sb3+掺杂量对ATO纳米球的光、电性能有很大影响，随着Sb3+掺杂量的增加其可见光透过率和电导率都呈现先增大后减小的变化关系。在nSb/nSn比为9∶100时其光电性能达到最佳。 | |

| Abstract: Sb-doped SnO2 (ATO) nanosphere was synthesized by the solvothermal route, starting with SnCl4·5H2O and SbCl3. The obtained samples were characterized by X-ray diffraction pattern, transmission electron microscopy, UV-visible transmission spectrophotometer and low-impedance surface impedance instrument. The results indicated that the 80~120 nm monodispersed ATO nanosphere was tetragonal structure, which was composed of numerous 5~10 nm ATO nanocrystallines. The Sb3+ doping content had a significant impact on optical property and electrical conductivity. With the increase of Sb3+ doping content, the transmittance in visible region and the conductivity were increased first, and then decreased. The preferable nSb/nSn molar ratio was 9∶100. | |
