N2 - Water soluble YVO4:Ln3+ and YVO4:Ln 3+/Ba2+ (Ln = Ce, Dy, Eu, and Sm) nanocrystals were synthesized by a poly vinylpyrrolidone-assisted hydrothermal method. Under the excitation of the host absorption, phosphors can emit blue light for YVO 4:Ce3+/Ba2+, yellow light for YVO 4:Dy3+/Ba2+, red light for YVO 4:Eu3+/Ba2+, and reddish orange light for YVO4:Sm3+/Ba2+. In comparison with those of YVO4:Ln3+ nanocrystals, the emissions of YVO 4:Ln3+/Ba2+ are greatly enhanced. Furthermore, the excitation spectra of YVO4:Eu3+/Ba2+ and YVO4:Dy3+/Ba2+ show the similar features, which are different from those of YVO4:Sm3+/Ba2+ and YVO4:Ce3+/Ba2+.
