摘要
利用传统陶瓷制备方法合成了ＳｒＡｌ２Ｏ４：Ｅｕ，Ｄｙ长余辉发光粉体，该磷光体主发射波长位于５２０ｎｍ，余辉时间长达８ｈ以上。并以硼硅酸盐低熔点玻璃为底材，掺杂该发光粉体，在一定温度下烧成，结果制得长余辉蓄光玻璃。研究还表明，烧成温度对该玻璃的发光性能影响较大，随着温度的升高，发光强度及余辉时间明显下降。
SrA2O4: Eu,Dy long afterglow luminescence powders are synthesized by the traditional ceramic synthesis method. The excitation peaks lie in 320nm and 360nm, and the emission peak lies in 520nm, the afterglow time may reach above 8h. Employed the low melt point B-Si glass as the matrix, doped the luminescence materials, and prepared the long afterglow luminescence glass. The results indicated the sintered temperature had great influence on the luminescent properties of the glass, as the temperature increasing, the luminescent intensity and the afterglow time decreased.
