中文摘要:
      本文采用溶胶-凝胶法合成了碱钨青铜(MxWO3,M=Cs、Rb中的一种或两种)粉体,探究了铯、铷分别单掺杂和铯、铷共掺杂对钨青铜粉体晶相、形貌的影响。利用X-射线衍射仪(XRD)、X-射线能谱仪(EDS)、扫描电子显微镜(SEM)、X-射线光电子能谱仪(XPS)、紫外可见近红外光谱(UV-Vis-NIR)、隔热膜温度测试仪对所合成碱钨青铜粉体的物相、形貌、光学性能和隔热性能进行了表征。结果表明: 溶胶-凝胶法所合成的碱钨青铜粉体结晶性较好、粒径较小且分散性较好;Cs、Rb共掺杂的透明绝热指数K=150.34比Rb单掺杂提高了23.92,改善了Cs单掺杂在1076nm处透过率突变的情况;Cs、Rb共掺杂的温差(与起始温度相比)为4.9℃比Rb单掺杂的温差下降了5.7℃。

英文摘要:
      In this paper, powders of alkali tungsten bronze (MxWO3, M=Cs, Rb or one of them) were synthesized by sol-gel method. The tantalum and niobium were respectively doped and yttrium and lanthanum co-doped to tungsten bronze. The effect of powder crystal phase and morphology. X-ray diffractometer (XRD), X-ray energy spectrometer (EDS), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), UV-visible near-infrared spectroscopy (UV-Vis-NIR) The phase, morphology, optical properties and thermal insulation properties of the synthesized alkali tungsten bronze powder were characterized by a thermal film temperature tester. The results show that the alkali-tungsten bronze powder synthesized by sol-gel method has good crystallinity, small particle size and good dispersibility. The transparent adiabatic index of Cs and Rb co-doped K=150.34 is higher than that of Rb single doping. 23.92, improved the Cs single doping at 1076nm transmission rate mutation; Cs, Rb co-doping temperature difference (compared to the starting temperature) is 4.9 ° C than the Rb single doping temperature difference decreased by 5.7 ° C.
