Abstract
A four-level decay model in KMgF3:Eu2+ is proposed. The decay profiles of the 6P7/2 excited state of Eu2+ are biexponential, and the physical implication of each term in the fit equation responsible for the model is interpreted. The evidence obtained spectroscopically for supporting the model is presented. A new method to study energy transfer between Eu2+ and X3+ in KMgF3:Eu−X (X = Gd, Ce, Cr) is established on the basis of the proposed model.
