以WCl₆、CsOH·H₂O和CrCl₃·6H₂O为原料，乙醇和乙酸为溶剂，通过水控制释放的溶剂热法一步合成Cr掺杂的铯钨青铜。通过X射线衍射仪（XRD）、X射线光电子能谱（XPS）、扫描电子显微镜（SEM）、能谱分析仪（EDS）、紫外-可见漫反射光谱（UV-Vis）对材料的晶相、结合能、形貌、元素组成等进行表征。结果表明，所合成的样品为六方Cs_0.32WO₃结构，随着Cr掺杂量的增加，薄膜的可见光透过率增加。当Cr/W摩尔比为0.01时，薄膜仍具有良好的红外屏蔽性能，而可见光区的平均透过率提高了10%。此外，通过隔热性能测试，与空白玻璃相比，薄膜的隔热温差为6.4℃，样品的隔热效率为73.4%。

A series of Cr-doped cesium tungsten bronzes are synthesized via water controlled-release solvothermal method using WCl₆,CsOH·H₂O and CrCl₃·6H₂O as raw materials,ethanol and acetic acid as solvents.The crystal phase,binding energy,morphology and elemental composition of the material are characterized by X-ray diffractometry (XRD),X-ray photoelectron spectroscopy (XPS),energy spectrum analyzer (EDS) and UV-visible diffuse reflectance spectroscopy (UV-Vis).The effect of Cr doping on the optical properties of cesium tungsten bronze is also investigated.The results illustrate that the synthesized samples have hexagonal Cs_0.32WO₃ structure and the transmittance of the film made from the samples increases with the increase of Cr doping amount.When the molar ratio of Cr/W=0.01,the film still exhibits good infrared shielding performance and the average transmittance in the visible light region increases by 10%.Furthermore,the heat insulation efficiency of the sample improves by 73.4%.In addition,through the thermal insulation performance test,the temperature variation of the film is 6.4℃ compared with a blank glass.
