Preparation of ultrafine multicolored fluorescent materials Sr2CeO4/Re(Re= Pr,Nd,Eu)by citrate-gel method

以柠檬酸为络合剂、乙二醇为稳定剂,在高温固相合成的Sr2CeO4中掺杂稀土元素Nd,Pr,Eu制备了Sr2CeO4/Re(Re=Nd,Pr,Eu)萤光材料.以SEM、XRD、萤光光谱等方法对其进行表征.Sr2CeO4/Re具有宽带的吸收和发射荧光光谱.紫外光能有效地激发其纳米荧光粉体,粒径大约分布在1～2μm之间,分散性较好,且具有从紫外到蓝绿光波段能量的吸收范围.激发光谱为300～480nm.该材料的发光强度大,发射主峰位于475nm.
