Abstract
CaSrS:Eu,Sm powders were prepared by wet-method in a reducing atmosphere. For application as an optical storage material, its spectra, such as emission spectrum, excitation spectrum, photostimulated spectrum, and thermal spectrum, were measured. The sample was stimulated by a 980 nm infrared laser after exposure to ultraviolet lamp (265 nm). The peak of the photostimulated spectrum is located at 615 nm. Its trap level is deep, and can make information stored stable. Optical storage mechanism of CaSrS:Eu,Sm is discussed.
