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