Paper Abstract

Photostimulated luminescence (PSL) in Eu and Sm co-doped II-VI compound phosphor ceramics such as SrS and CaS is studied in order to develop a smart erasable and rewritable optical memory utilizing PSL phenomenon. Intense PSL with a peak at about 600 nm and 650 nm is observed, respectively, in SrS:Eu,Sm and CaS:Eu,Sm posphor ceramics which are stimulated with infrared light after irradiation with ultraviolet-(UV) light or visible-light. The PSL characteristics of SrS:Eu,Sm posphor ceramics for the optical memory are reported. The OR Boolean logic operation is demonstrated using the PSL phenomenon in photostimulable phosphor materials.
