Energy transfer studies of Dy 3+ ions doped K 2 GdF5 crystal

Dy3+-doped K2GdF5single crystals were synthesized under hydrothermal condition. The UV excitation spectra and lifetimes of K2GdF5:Dy3+ were measured at room temperature. The excitation spectra have shown charge transfer state(CTS) of Dy3+and energy transfer from Gd3+to Dy3+ions in K2GdF5:Dy3+crystal. The decay curve of the K2GdF5sample doped with 5.0 mol % Dy3+ions is a non – exponential curve and is well fitted to the Inokuti – Hirayama model for S= 6. The energy transfer parameters (Q, CDA) and the critical distance (R0) are calculated
