Abstract

The absorption spectrum, upconversion spectrum and the fluorescence decay curve of Er³⁺/Yb³⁺ co-doped KY(WO₄)₂ crystal were measured. The radiative transition rates were calculated by Judd-Ofelt theory. A model for the dynamics of frequency upconversion process in Er³⁺/Yb³⁺ co-doped KY(WO4)2 crystal was proposed. The Yb-to-Er energy transfer rate and the upconversion coefficients were estimated by numerically solving the rate equations and fitting simulated curve to the experimental data.
