Temperature dependence of upconversion luminescence from Pr~(3+) and Yb~(3+) codoped ZBLAN glass umped by 960 nm laser diode

摘要

In this paper, the temperature dependence of upconversion luminescence from Pr~(3+) and Yb~(3+) codoped ZBLAN glass pumped by 960 nm laser diode was studied. In our experiments the temperature was changed from room temperature (24 deg C) to 300 deg C. The results show that not only luminescence intensity but also upconversion spectrum configuration changes with the increase of temperature. In the range of temperatures we were interested in, the intensity of upconversion luminescence first increases with temperature, and arrives at its maximum, then decreases.
