The diammonium phosphate was added as start material to synthesize Pdoped BaMgAl10O17:Mn2+ phosphors, which were prepared by high temperature solid state technology. The effect of Pdoping on the structure, morphology and luminescent properties of BaMgAl10O17:Mn2+ were determined by Xray diffraction, scanning electron microscopy, Fouriertransform infrared spectroscopy, energy dispersive Xray spectroscopy and vacuum ultraviolet VUV spectra. The results show that P doping is conducive to the crystallization of the phosphors and improving the morphology. The lattice parameters become smaller when the phosphor is doped with P. The P doping makes the emission spectra to blueshift and the CIE x value to decrease. At appropriate P concentration, the absorption of the matrix in VUV range is improved, and the emission intensity under VUV excitation is enhanced.
