摘要:
Spectroscopic properties of Er3+-singly doped SiO2--BaF2-ZnF2 glass have been investigated on the basis of the Judd-Ofelt theory. Upconversion emissions in Er3+/Yb3+-codoped SiO2-BaF2-ZnF2 glass have been observed under 980 nm excitation. The temperature dependence of fluorescence intensity ratio corresponding to the two thermally coupled levels (H-2(11/2), S-4(3/2)) has been studied and it is concluded based on the results that the method can be possibly applied for temperature sensing.
