摘　　要：为得到热稳定性能良好且高强度发光的碲酸盐玻璃,通过在TeO_(2)-ZnO-Na_(2)O系统中掺入WO_(3),以提高玻璃的抗析晶和热稳定性能。研究结果表明,碲酸盐玻璃的ΔT从不掺WO_(3)的110℃增加到了WO_(3)含量为20 mol%时的142℃。在热稳定性研究的基础上,进一步分别研究了单掺Er^(3+)和Er^(3+)/Yb^(3+)共掺的碲钨酸盐玻璃的光谱性质。研究结果表明,在Er^(3+)/Yb^(3+)共掺条件下,Er^(3+)/Yb^(3+)之间的能量传递提高了Er^(3+)离子对980 nm泵浦光的吸收效率,增强了1.5μm波段发光强度,最终得到了具有高强度1.5μm波段发光的Er^(3+)/Yb^(3+)共掺碲钨酸盐玻璃,初步证明共掺方式是实现1.5μm波段高强度发光的有效方法。In order to obtain the tellurite glass with good thermal stability and high-intensity luminescence,WO_(3) is doped into the TeO_(2)-ZnO-Na_(2)O system to improve the anti-devitrification and thermal stability of the glass.The results show that theΔTof the tellurite glass increases from 110°C without WO_(3) to 142℃ with WO_(3) content of 20 mol%.On the basis of thermal stability study of tellurite glass,the spectral properties of single-doped Er^(3+)and Er^(3+)/Yb^(3+)co-doped tellurium tungstate glasses are further studied.The research results show that under the co-doping conditions of Er^(3+)/Yb^(3+),the energy transfer between Er^(3+)/Yb^(3+)improves the absorption efficiency of Er^(3+)ions for 980 nm pump light,and the luminescence intensity in the 1.5μm band is enhanced.Finally,Er^(3+)/Yb^(3+)co-doped tellurium-tungstic glass with high-intensity 1.5μm band emission is obtained,indicating that the co-doping of Er^(3+)/Yb^(3+)is an effective method to achieve high-intensity luminescence in the 1.5μm band.
