| 摘 要： | 用高温熔融法制备了Tm3+/Ho3+/Yb3+共掺碲酸盐玻璃样品,在TeO2-ZnO-La2O3玻璃组分的基础上,引入声子能量较低的重金属氧化物Bi2O3,研究了Bi2O3组分对基质样品拉曼光谱和Tm3+/Ho3+/Yb3+共掺样品上转换发光光谱的影响。结果发现,在975 nm波长激光二极管(LD)激励下,制备的碲酸盐玻璃样品中可以观察到强烈的红光(662 nm)、绿光(546 nm)和蓝光(480 nm)三基色上转换发光。随着重金属氧化物Bi2O3组分含量的增加,玻璃基质的最大声子能量降低,Tm3+/Ho3+/Yb3+共掺样品的三基色上转换发光强度均有所提高,且Bi2O3组分的引入对上转换蓝光发光强度的影响要大于其对绿光和红光的影响。

| Abstract: | Tm3+/Ho3+/Yb3+-codoped tellurite glasses are prepared by conventional melt-quenching method.The heavy metal oxide Bi2O3 with lower phonon energy is introduced into the tellurite glass with a composition of TeO2-ZnO-La2O3,and the effect of the Bi2O3 content on the Raman spectra of the matrixes and the upconversion luminescence spectra of the Tm3+/Ho3+/Yb3+-codoped samples are studied.The results show that the intense red(662 nm),green(546 nm) and blue(480 nm) emissions of the tellurite-based glasses are simu... |
