ABSTRACT:
A quantum-splitting fluoride-based phosphor comprises gadolinium, at least a first alkali metal, and a rare-earth metal activator. The phosphor is made in a solid-state method without using HF gas. The phosphor can be used alone or in conjunction with other phosphors in light sources and displays wherein it can be excited by VUV radiation, and increases the efficiency of these devices.
