摘要： CdS和ZnS相似,都有立方和六方两种结构.ZnS在低于102℃时立方型稳定,高温稳定相是六方型;CdS从立方转变为六方构型的温度约在600℃左右. CdS-ZnS固熔体由于在光电和荧光材料等方面有广泛的应用,而引起人们的兴趣,但是由于制备方法和条件的差异,常有不同的结果.过去的工作表明,在灼烧中,导电性材料In2O3不影响固熔体的结构,同时(CdxZn1-x)S:Ag/In2O3的低压荧光光谱随着CdS与ZnS比例的变化而变化.本文继续研究这种光谱与荧光基质CdS-ZnS固熔体晶格参

Abstract: The structure of (CdxZn1-xS:Ag obtained by sintering at 8500 was determined by X-ray diffraction method,The solid solution is of homogeneous wurtzite over the range of 0,5x from 0.3 to 0,the fraction of Zn-rich sphalerite increases gradually till all the structure becomes of sphalerite, The lattice parameters vary with the composition of the solution and it results in a variation of luminescence emission spectra, The phase transition from the sphalerite to wurtzite occurs at about 700℃ with simultaneous formation of the luminescence center.
