Luminescence characteristics of the materials for the devices representation of information

摘要

Studied luminescence characteristics of the new materials for the electroluminescence displays and optical storage devices Optically Stimulated luminescence in Cao: Eu, Sm and Mgo : Eu, Sm have been studied. On Optically Stimulating an UV treated sample, The trapped electrons are released by Sm2+ ions and are recaptured by Eu3+ ions Leading to the Luminescence which is characteristic of Eu emission
