摘要/描述

Energy transfer processes between Eu2+ and GD3, CR3+, Ce3+ ions in KMgF3 which are difficult to study spectro-scopically, have been investigated by using the proposed four-level decay model of the 6P7/2 escited state of the Eu2+ ion. GD3+ AND Ce3+ transfer its energy to the vibronic transition of the 6P7/2→S7/2 transition of Eu2+, whereas Cr3+ receive energy from Eu2+ 4f65d level to the Ce3+ 4f5d state is observed spectroscopically, and the energy transfer mechanism is discussed.
