| 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。

| Abstract: | The long afterglow phosphor CaAl2O4:Eu2+,Nd3+ was prepared by combustion 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 product was CaAl2O4 with monoclinic crystal structure.The addition of PEG increased the initial brightness of long afterglow phosphar CaAl2O4:Eu2+,Nd3+,but didn′t prolong its afterglow time. |
