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.
