Mechanisms for the cathodoluminescence of cerium-doped yttrium aluminum garnet phosphors

摘要

Abstract: We examine the luminescent properties of cerium-doped yttrium aluminum garnet (Ce:YAG) under cathodoluminescence. The cerium emission is strongly affected by the presence of intrinsic defects it the crystal. We show that a model based on non-radiative energy transfer is compatible with the results obtained from cathodoluminescence experiments. !
