YVO4:Bi3+,Eu3+ nanophosphors are prepared by low-temperature wet chemical precipitations in the presence of citrate ions. Transparently dispersed YVO4:Bi3+,Eu3+ nanophosphors crystallize from amorphous gel precursors through a gel-sol process. The homogeneity of Bi3+ doping process as well as the photoluminescence property are improved by using the homogeneous Bi3+ solution as a Bi3+ source instead of Bi3+ powder. YVO4:Bi3+,Eu3+ nanophosphor under the irradiation of near-UV light shows peculiar photobleaching behavior through the reduction from V5+ to V4+, but this photobleach is suppressed by subsequent hydrothermal treatment. The authors also discuss the advantage of transparency of YVO4:Bi3+,Eu3+ nanophosphor in terms of wavelength conversion as compared to micron-sized phosphor.
