摘　　要：为了得到显色改善的绿色和红色发光玻璃,本文采用高温熔融技术制备了Tb^3+/Gd^3+/Ce^3+/Sb^3+和Eu^3+/Bi^3+/Sb^3+共掺杂的硼硅酸盐透明玻璃。通过对共掺样品紫外可见吸收光谱的分析和长波紫外激发下的激发光谱及荧光光谱的分析,研究了Tb^3+/Gd^3+/Ce^3+/Sb^3+和Eu^3+/Bi^3+/Sb^3+共掺杂离子在玻璃基质中的发光性能,结果表明,在高能紫外光激发下,Tb^3+/Gd^3+/Ce^3+/Sb^3+共掺杂样品发射典型纯正绿光荧光的能力较强,Eu^3+/Bi^3+/Sb^3+共掺杂样品发射红光荧光的能力较强。We prepared transparent borosilicate glass co-doped with Tb3+/Gd3+/Ce3+/Sb3+and Eu3+/Bi3+/Sb3+by high temperature melting technologyin order to obtain green and red luminescent glass with improved color rendering.The luminescence properties of rare earth ions in glass substrate were studied by analyzing the UV visible absorption spectra of co-doped samples and the excitation spectra and fluorescence spectra under long wave UV excitation.The results show that Tb3+/Gd3+/Ce3+/Sb3+co-doped borosilicate transparent glass can emit typical pure green light under long wave UV excitation,and Eu3+/Bi3+/Sb3+co-doped samples can emit strong red light under long wave UV excitation.
