摘　　要：本文以乙二醇为溶剂及配位剂,以冰乙酸为酸性催化剂,采用溶胶-凝胶法制备均一稳定的具有不同锑掺杂浓度的二氧化锡(Sn O_2)溶胶,再通过红外灯辅助喷雾热解法制备性能优异的可控锑掺杂Sn O_2薄膜,并对薄膜微结构、光电性能进行表征。结果表明:薄膜以四方金红石结构存在,结晶完全;方阻值随锑掺杂浓度和成膜厚度的增加而降低;薄膜在可见光区的平均透过率可达79%左右,且在中远红外光区的平均反射率可达80%左右。此外,通过改变锑掺杂浓度和成膜厚度,能够有效地调节薄膜的红外反射率与反射起点波长,从而满足不同气候条件对热反射和热发射的不同要求。Antimony-doped tin oxide (ATO) sol was prepared by using glacial acetic acid as acidic catalyst and ethylene glycol as ligand and solvent via sol-gel method, which was further utilized to fabricate high-quality Sb controllable doped ATO thin films using spray pyrolysis with an infrared lamp as the assistant heater. The structures, electrical and optical properties of these ATO thin films were systematically investigated. The X-ray diffraction (XRD) analysis revealed that the ATO thin films retained the tetragonal rutile structure with high crystallinity. The resistance of these thin films decreased with the increase of Sb doping level and film thickness. The average transmittance for the ATO thin films in visible range was about 79 %, and the average reflectance in the infrared range was about 80%. Furthermore, the infrared reflectance and emissivity of the thin film can be effectively adjusted by varying the Sb doping concentration and film thickness, which can meet the needs of different climatic conditions.
