采用高温熔融法制备了两系列不同掺杂比的Er

3+
共掺的碲酸盐玻璃
测试了样品的吸收光谱和在980 nm LD激发下的发光光谱、上转换发光光谱及发光寿命。讨论了Er

与Tm

掺杂浓度对样品光谱性质的影响
Tm

离子的掺入会减弱Er
3+
的1.53 μm发光强度
但通过共振能量传递可以获得Tm

的1.8 μm发光
并随着Tm
3+
离子浓度的增加而增强。同时表明Tm

离子的增加会减弱Er

离子在528 nm和545 nm附近的上转换绿光强度
而上转换红光出现了先增强后减弱的现象。研究了Er

The Er

-codoped tellurite glasses were prepared by high-temperature melting. The absorption spectra
fluorescence spectra
upconversion emission
and the fluorescence lifetime of samples were investigated under 980 nm LD excitation. Spectral properties of the samples with different concentration of Er

-Tm

ions were analyzed
the 1.53 μm fluorescence intensity of Er
3+
reduces with increasing Tm

but the 1.8 mm emission of Tm

increases. The Tm

from 0.1% to 0.5% where Er

mol fraction is fixed at 0.5%
while the energy transfer rate

from Er

to Tm
3+
increases rapidly and then tardily does. The upconversion luminescence of Er
3+
and Er
3+
/Tm
3+
ions doped tellurite glasses was investigated. The green light of 530 nm and 545 nm
and the red light of 657 nm can be observed in Er
3+
doped tellurite glass
moreover the 545 nm light intensity is stronger than the 530 nm light. But the green upconversion emission intensity decreases with Tm
3+
-ions doping
otherwise the red upconversion emission intensity increases firstly and then decreases with increasing Tm
3+
-ions concentration. In addition
the intensity of red light is strongest when the Tm

/Er
3+
concentration ratio is 1/5 approximately.
