Abstract
The absorption spectra and the luminescence decay curve of Er3+/Yb3+ co-doped KY(WO4)2 crystal was measured. The radiative transition rates were calculated by Judd-Ofelt theory. The Yb-to-Er energy-transfer rate and the cooperative upconversion coefficients were estimated by numerically solving the rate equations and fitting simulated curve to the measured data.
