KSrScSi2O7:Eu2+: a novel near-UV converting blue-emitting phosphor with high efficiency and excellent thermal stability

Abstract

A novel blue-emitting phosphor KSrScSi2O7:Eu2+, synthesized from a water-soluble propylene glycol modified silane (PGMS) silicon precursor by a solution approach, exhibits high internal quantum efficiency and remarkable thermal stability, which are attributed to the rigid structural network of the host and weak electron-phonon coupling strength.
