Abstract:	Two unprecedented phosphors, CaZnOS:Eu2+ and Sr8Al12O24S2:Eu2+, were prepared and investigated. The PL spectra of both reveal a broad emission band extending from 550 to 700 nm under blue light pumping Both phosphors exhibit superior stability than SrS:Eu2+ in thermal quenching up to 120 degrees C and great potential for LED application.
