摘　　要：选择铝硼硅酸盐玻璃体系，高温熔融法制备了Eu，Dy掺杂的铝硼酸盐基质透明玻璃，并采用槽沉法制备了透明玻璃微球．利用XRD、SEM和荧光光谱对样品进行分析．结果表明：该玻璃微球粒径分布范围窄，光学性能好，其折射率为1．690；单掺杂和双掺杂玻璃微球均具有长余辉发光性能，单掺杂Eu^2＋发光峰位于460nm，而双掺杂Eu^2＋、Dy^3＋的发光峰分别位于456和452nm，并且样品的发光时间达到15h以上。The luminosilicate glass microspheres doped with Eu2O3 and Dy2O3 were prepared using the sagging method under the reducing atmosphere and characterized by X-ray diffraction（XRD）, scanning electron microcopy（SEM）, the excitation spectra and emission spectra. Research results indicate： The refractive index is 1.690. The glass microsphere doped with Eu^2＋ shows luminescence peaking at 460nm. The glass microspheres doped with Eu^2＋ and Dy^3＋ shows luminescence peaking at 456nm and 452nm respectively. The afterglow luminescence can last more than 15h.
