ZnWO4:Eu3+ nanorods: A potential tunable white light-emitting phosphors

▶ Tunable color from blue through white to orange could be obtained by adjusting the doping concentration of Eu3+ from one-dimensional ZnWO4:Eu3+ nanorods by a facile template-free hydrothermal route. A nearly ideal white light of ZnWO4:0.5% Eu3+ with CIE coordinates of (x = 0.32, y = 0.30) and color temperature of 5919 K implies the potential applications in UV LEDs for phosphors converted white light-emitting diodes (pc-WLEDs).
