In present paper the effect of dopant on the crystallite size, morphology and the photoluminescence of the sample were also investigated with X-ray spectrometer (XRD), Fourier-transform infrared spectroscopy (FTIR).The phosphors were synthesized using the standard solid state reaction technique and ground using mortar and pestle, fired at 1200oC for 1 hour in a muffle furnace. We have studied the effect of dopants on the Photo luminescent properties of the samples using Spectrofluorophotometer at room temperature. PL emission of undoped LaPO4 phosphor was observed at 470 nm. Under the excitation of 254nm wavelength, PL emission of doped LaPO4 phosphor shows peaks at 589, 596, 614 and 622nm with good intensity.
