Abstract

In this work, an Eu²⁺-doped K₃ScSi₂O₇ (KSSO) NIR phosphor with broad-band NIR emission and robust thermal stability was designed and synthesized successfully. The crystal structure, luminescent properties, the mechanism of abnormal NIR emission, thermal stability and application to NIR pc-LEDs were investigated in detail.
