摘要
采用燃烧法合成了CaAl2O4:Eu2+,Nd3+长余辉发光材料,研究了PEG(聚乙二醇)对其发光性能的影响。采用X-射线衍射(XRD)、荧光光谱对发光材料进行了表征。结果表明,燃烧产物主晶相为单斜晶系的CaAl2O4;PEG的添加有效提高了CaAl2O4:Eu2+,Nd3+长余辉发光材料的初始亮度,但余辉时间没有得到延长。
The long afterglow phosphor CaAIz O4 EU2＋, Nd3＋ was preparea Dy comousuon synthesis,and the influence of PEG on its luminescent properties was studied. The samples were characterized by X-ray diffraction （XRD） and fluorescence spectroscopy. The results showed that the main phase of the combustion prod- uct was CaA1204 with monoclinic crystal structure. The addition of PEG increased the initial brightness of long afterglow phosphar CaAl2O4 ：Eu2＋ ,Nd3＋ ,but didnrt prolong its afterglow time.
