INVESTIGATION OF FLUORESCENT DYNAMICS ON Er x Y 1-x AlO 3 CRYSTALS

In this paper, the radiative transition probability, non-radiative transition probability, cross relaxation probability and other spectral parameters are calculated in detail. By considering three kinds of radiative processes, the fluorecent dynamic process is discussed, the relations between the fluorescent character and the concentrations of Er 3+ ions are studied, and their laws are given.
