A comprehensive model which can predict the Ho3+ 5I7 YAG (Y3Al5O12) manifold luminescence and radiative energy transfer rate among Ho ions for a given concentration and emission path length within the crystal has been developed. Independently, a model was devised to calculate these rates using measured lifetimes as well as calculated radiative and non-radiative lifetimes. The rates of radiative energy transfer were determined from both of these models and found to be in close agreement.
