Abstract
It is shown that the mutual static crystal field perturbation produced by the sensitizer and activator ions at each other's site could modify both the radiative and energy transfer characteristics for near sensitizer-activator pairs in co-doped crystals. These effects modify the spectral and temporal characteristics of the activator emission in the sensitized systems. The implication of these static effects on the estimation of sensitizer-activator transfer efficiency by using the luminescence decay of the donors is also discussed.
