Green-emitting phosphors doped with Ce and Tb have been synthesized for the first time by reaction of BPO 4, prepared in our laboratory,with rare earth oxides. It is qualitatively accounted for that the prepared phosphors belong to borophosphate,and replacement of P with B doesn’t cause variation of monoclinic crystal system of orthophosphate.XRDs of the samples prepared at different temperatures show that the product is formed at 850℃.The primary investigation of luminescent of phosphors indicates that with the increment of Tb content,the brightness and purity of luminescent will be improved.
