Abstract: Non-rare-earth Mn4+-doped double-perovskite (Ba1- xSr x)2YSbO6:Mn4+ red-emitting phosphors with adjustable photoluminescence are fabricated via traditional high-temperature sintering reaction. The structural evolution, variation of Mn4+ local environment, luminescent properties, and thermal quenching are studied systematically. With… read more here.
