摘　　要：采用固相反应法在800℃烧结制备出了不同锡掺杂量的(In1-xSnx)2O3(x=0,0.01,0.02,0.05)粉体,通过X射线衍射仪(XRD)、拉曼光谱仪、傅里叶红外光谱仪(IR)、紫外吸收可见光谱(Uv-vis)分析仪以及扫描电镜(SEM)等对(In1-xSnx)2O3粉体的结构、光学性能和形貌进行了表征。结果表明:不同锡掺杂量的(In1-xSnx)2O3粉体都保持了In2O3的立方相晶胞结构;锡的掺杂改变了In2O3的紫外-可见吸收性能和红外吸收性能,抑制了In2O3粉体颗粒的长大,使其结构变得更加紧密。（In1-xSnx）2O3（x=0,0.01,0.02,0.05）powders with different Sn-doping amounts were prepared by solid state reaction at 800 ℃.The structure,optical properties and morphology of（In1-xSnx）2O3powders were characterized by X-ray diffraction（XRD）,Raman spectroscopy,Fourier transform Tnfrared（IR）spectroscopy,ultraviolet visible（Uv-vis）absorption spectrophotoscopy and scanning electron microscopy（SEM）in detail.The results show that all the（In1-xSnx）2O3 powders with different Sn-doping amounts remained the cubic crystal structure of indium oxide,and its UV-vis and IR absorption properties were changed by the Sn-doping,the growth of In2O3 particles was restrained,and thus their structure became more closely.
