Optical and Electrical Properties of SrAl[sub 2]O[sub 4]:Eu[sup 2+]
Source abstract
Abstract
It has been shown that the optical and electrical properties of depend on composition. A composition with excess alumina was found to have the highest CR efficiency, photoconductivity, and a long‐lasting persistence. A mechanism is proposed which assigns the delayed luminescence to a process involving the conduction of charged particles. Evidence is presented which indicates that holes are trapped at lattice defects and the Eu 2+ emission is associated with thermal deactivation of these traps.
