Abstract

The upconversion fluorescence spectrum and the luminescence decay curves from transitions of ⁴I_13/2→⁴I_15/2 and ⁴I_11/2→⁴I_15/2 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 ⁴I_13/2+⁴I_13/2→⁴I_9/2+⁴I_15/2 and the upconversion coefficient C₃₃ for the cross relaxation ⁴I_11/2+⁴I_11/2→⁴I_15/2+⁴F_7/2 were 0.91×10^-18cm³/s and 18.23×10^-18cm³/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.
