采用高温固相合成法制备了Y1-xVO4:Dy3+x和Y0.994-yVO4:Dy3+0.006,Eu3+y系列样品，通过XRD确定其晶体结构.对它们荧光性质的研究发现，Dy3+在YVO4中可同时发射出483 nm（蓝光）和573 nm（黄光）荧光，分别归属于4F9/26H15/2和4F9/26H13/2的能级跃迁，且Dy3+在Y1-xVO4:Dy3+x样品中的最佳浓度为0.006（摩尔比）.对于Dy3+/Eu3+共掺Y0.994-yVO4:Dy3+0.006,Eu3+y样品，当Eu3+浓度在0～0.004（摩尔比）区间内，它只敏化Dy3+发光，而自身不发光.超过0.004后，敏化作用不显著，以Eu3+发光为主.此时的样品同时发射出蓝光（483 nm）、黄光（573nm）和红光（620 nm），组合后可获得色纯度更好的白光.
The phosphors with the compositions of Y1-xVO4:Dy3+x and Y0.994-yVO4:Dy3+0.006,Eu3+y were synthesized by a high temperature solid state reaction method. Their crystal structures were checked by X-ray diffraction (XRD) technique. The luminescent properties of Y1-xVO4:Dy3+x phosphors have been investigated. The characteristic emission peaks of Dy3+ due to the transitions of 4F9/26H15/2 at 483 nm and 4F9/26H13/2 at 573 nm were observed in the emission spectra. The optimal concentration of Dy3+ in Y1-xVO4:Dy3+x phosphors is 0.006 (mol ratio). The luminescent intensities of Dy3+ in Y0.994-yVO4:Dy3+0.006,Eu3+y phosphors enhance markedly, synchronously, the intensities of Eu3+ are zero when the concentration of Eu3+ is in the range of 0 to 0.004. It is clear the luminescence of Dy3+ ions were sensitized by Eu3+. When the concentration of Eu3+ over 0.004, the luminescent emissions of Dy3+ and Eu3+ ions for Y0.994-yVO4:Dy3+0.006,Eu3+y phosphors have been monitored, the combination of blue (483 nm), yellow (573 nm) and red (620 nm) emission bands was shown, and white light emission can be observed under UV light excitation.
