A series of LED white phosphors NaGd1－x－y(MoO₄)₂:xDy3＋yTm3＋ were synthesized by high temperature solid state method.The phase structure and luminescence propert ies of samples were investigated by X-ray diffractometer (XRD),fluorescence spectrophotometer and UV-Vis-NIR spectroscopy.The results show that the white light of the prepared phosphor is composed of the characteristic yellow light emission (575nm) of Dy3＋,th e characteristic blue light emission (488nm) and the characteristic blue light emission (459nm) of T m3＋.The prepared NaGd(MoO₄)_2substrates are all scheelite structures,the activated ion Dy3＋ emits ⁴F9/2－⁶H13/2 transition yellow light (575nm) and the blue light of ⁴F9/2－⁶H15/2 transition (488nm),the blue light transition of the activated ion Tm3＋ emitting ¹D₂－³F ₄ (459nm) is a non-sensitive transition,and the blue light emission is reduced to two emission peaks by the influence of the cry stal field.that when the phosphor is excited at 389nm,when the concentration of Dy3＋ is 10%, t he concentration of Tm3＋ is 12%,the sample is closest to the standard white light (0.33,0.33),and when the concentration of Dy3＋ is 8%,the concentration of Tm3＋ is 12%,the luminescence intensity of the sample reaches the maximum,the color coordinate is (0.3777,0. 3696).The results show this series of phosphors has potential development and application prospects.
