Effects of excitation wavelength and Y3+ content on luminescent properties of YMO4:Dy3+ (MÂ =Â V, P) phosphors induced by ultraviolet excitation

► The color temperature of YPO4:Dy3+ phosphor can be controlled by changing excitation wavelength. ► YxVO4:Dy3+ phosphors were synthesized by chemical precipitation method. ► Little excessive Y3+ content can make body color of YVO4:Dy3+ phosphor become white even if sintered above 1100 °C.
