摘　　要：目的:微波快速制备复合基质荧光体CaxSr(1-x)S:Mn,测定其荧光光谱并研究它们随基质摩尔掺杂比x(即Ca2+/Ca(2+)+Sr2+)值由1逐渐减小到0的变化,探求制备荧光颜色可调的荧光体的原理。方法:微波快速加热法。内容:通过XRD的测定,确定了含有不同x值的CaxSr(1-x)S:Mn的晶相。测定荧光光谱,研究它们随x值的变化趋势。结论:随着x值由1逐渐减小到0,荧光体CaxSr(1-x)S:Mn由单一的CaS相转变为CaS和SrS的混合相再逐渐变为SrS相,其荧光光谱也由CaS的特征光谱逐渐转化为SrS的特征光谱。根据CaxSr(1-x)S:Mn的发射波长与x值基本呈线性关系,可通过调节基质掺杂比,制备荧光颜色可调的荧光体。Objective: Rapidly synthesizing the mixing host phosphors CaxSr1-xS:Mn by microwave radiation method (MRM), measuring their fluorescent spectra, studying the variation of their fluorescent spectra with x (Ca2+/Ca(2+)+Sr2+) value changing from 1 to 0, in order to find the principle of making phosphors whose fluorescent colors can be adjusted.
