Paper Abstract

The upconversion fluorescence spectrum and the luminescence decay curves from transitions of 4I13/24I15/2 and 4I11/24I15/2 in the Er3+-doped PLZT transparent ceramic were measured experimentally. A model for the dynamics of frequency upconversion in Er3+-doped PLZT transparent ceramic based on the rate equations was proposed. The dynamics of the upconverted emissions were studied to evaluate energy transfer (ET) rates by solving the rate equations of the model and fitting the experimental curves. The upconversion coefficient C22 for the cross relaxation 4I13/2+4I13/24I9/2+4I15/2 and the upconversion coefficient C33 for the cross relaxation 4I11/2+4I11/24I15/2+4F7/2 were 0.91×10-18 cm3/s and 18.23×10-18 cm3/s, respectively. The model provides a good basis for explaining the experiment data because it shows a high sensitivity to the input fitting parameters. The analysis reveals that Er3+-doped PLZT transparent ceramic have a great prospect to be applied for monolithic multifunction compact devices and upconversion devices.
