Abstract
Luminescence spectra of erbium ions doped in Y2O3-P2O5 thin films, with different P2O5 content (from 3% to 47%), were analysed with crystal-field Hamiltonian model with D2d symmetry including J-mixing effect. The empirical crystal-field parameters (CFPs) obtained for the best fit of calculated to experimental energy levels allows us to confirm the well-established YPO4 phase for 47% of P2O5. The CFPs are compared to those calculated for Ce3+, Nd3+ and Dy3+ in the YPO4 host. This work is a continuation of our previous results for erbium-doped Y2O3 thin films.
