Abstract

The upconversion fluorescence spectra of Er3+/Yb3+: PLZT exciting at 980nm were measured from 10K to 320K. A model for the dynamics of upconversion processes was proposed. Based on the model, the upconversion luminescence intensities curves with different temperature were fitted and the temperature characteristics of upconversion luminescence were discussed.
