Preparation and Luminescence Properties of Dy<sup>3+</sup> Doped Sr<sub>3</sub>Lu(PO<sub>4</sub>)<sub>3</sub> as a New Single Phase White Light Emitting Phosphor

Abstract: The novel white light emitting phosphors Sr3Lu(1-x)Dyx(PO4)3 (x = 0.02, 0.04, 0.06, 0.08, 0.10) were synthesized via a conventional high-temperature solid-state reaction method at 1250°C. The excitation spectrum indicated that these phosphors had a strong absorption in near UV region in the range from 260 to 460 nm. And under 350 nm excitation, the blue emission at 483nm (4F9/2→6H15/2) and yellow emission at 576 nm (4F9/2→6H13/2) were observed in the phosphors, respectively. We studied the effect of different … Show more
