以SnCl4·5H2O和SbCl3为原料，采用共沉淀法制备不同Sb掺杂量的氧化锡锑(ATO)纳米粉末。分别采用XRD、FESEM、紫外可见分光光度计和激光器对晶体结构、形貌、激光反射率进行表征，研究Sb掺杂量对ATO纳米颗粒的结构、晶粒尺寸和激光反射性能的影响。结果表明：共沉淀法制备的 ATO 纳米颗粒为四方相金红石结构，粒径大小约为几十纳米；随着Sb掺杂量的增加，ATO的晶粒尺寸减小，晶胞体积则逐渐增大；与未掺杂的SnO2粉末相比，Sb掺杂后的ATO粉末在1.06μm激光波长处的反射率明显低于未掺杂的SnO2的反射率；随着Sb掺杂量的增加，反射率值呈先减小后增大的趋势，在Sb掺杂量为20%时， ATO粉末在1.06μm激光波长处的反射率低于0.02%，激光隐身性能最佳。

Antimony tin oxide (ATO) nano-particles doped with different Sb contents were prepared by co-precipitation method, using SnCl4·5H2O and SbCl3 as main raw materials. Microstructure, morphology and reflectivity curves were characterized by XRD, FESEM, UV-visible spectroscopy and laser, and the effects of Sb content on crystalline microstructure, crystal size and reflectivity curves of the ATO nano-particles were investigated systematically. The results show that the ATO nano-particles prepared by co-precipitation method have tetragonal rutile structure, with particle size distribution range of several decade nanometer. With the increase of Sb content, the grain size of ATO decreases, and the unit cell volume increases. Compared with the SnO2 particles without Sb, the 1.06 μm laser reflection of ATO nano-particles doped with Sb is obviously lower. With the increase of Sb content, the reflection increases first, then decreases;when the Sb content is 20%, 1.06μm laser reflection of ATO nano-particles is below 0.02%, and the laser reflection performance is the best.
