Abstract
A study is reported of the codoping of SrS:Ce by Ag and Cu in order to achieve charge compensation of the trivalent Ce atom. Both Ag and Cu codoping produced a blue shift in the photoluminescence spectra and mu ch higher electroluminescent device performance. These improvements we re attributed to the substitutional incorporation of Ag and Cu onto th e Sr lattice site which minimized the vacancy formation and provided c harge compensation.
