Abstract

By solid-state reaction and doping, a series of red-emitting phosphors Na<sub>x</sub>Y<sub>0.92–x/3</sub>(MoO<sub>4</sub>)<sub>y</sub>(WO<sub>4</sub>)<sub>1–y</sub>O<sub>0.5</sub> : zEu<sup>3+</sup> have been synthesized. Through optimization of the process conditions and photoluminescent analysis, one type of red emission is obtained that matches nicely with ultraviolet light-emitting diode (UV-LED) chips.
