Abstract
- Abstract: The effect of temperature on the luminescence intensity of up-conversion and near infrared in Er3+/Yb3+ co-doped phosphate glass ceramics has been investigated. Efficient green and red up-conversion luminescence and strong infrared fluorescence at 1.54μm wavelength are observed under excitation of 975nm. The fluorescence intensity is changing at different temperature and the results are explained with the level transitions in Er3+/Yb3+ co-doped system. Meanwhile, the lifetime of Er3+:4I13/2 level corresponding to different operating temperature and pump power is also discussed, and the experimental results are fitted using multiphonon relaxation theory.
