Abstract

In this paper electron trapping optical storage materials CaS: Eu, Sm was prepared by high temperature solid state method. XRD analysis indicates that the sample obtained is with face-centered cube structure. with a lattice parameter of 5.694A. Optical properties of CaS: Eu, Sm were studied. Excitation spectrum shows that the material can be excited by ultraviolet and visible light. The excitation peaks are at 250-300nm and 450-550nm respectively ranging from 250-550nm. Emission spectrum is composed of three peaks at 567nm, 603nm and 650nm respectively. Photo-stimulation excitation spectrum is a broadband spectrum between 800nm and 1600nm peaking at about 1200nm. Photo-stimulated luminescence peak is at 635nm.
