Abstract
This paper reports the luminescence effects of Tm3+ doped YVO4:Dy nanocrystalline synthesized by a modified Pechini method. The structure and morphology were characterized by using X-ray diffraction (XRD) and transmission electron microscope (TEM). The relationship between the ratio of Tm3+/Dy3+ and the chromaticity is studied, i.e. Tm3+ ion doping effectively tunes the emission color of YVO4:TmxDy1−x phosphors. The best white light emission was observed with YVO4:1%(Tm0.6Dy0.4). These results indicate that thulium doped YVO4:Dy phosphors are promising white-emitting luminescence materials.
