Abstract: A series of CexTb1-xP5O14: Mn erystals have been grown from phosphoric acid solution by an evaporation mcthod. The structure of crystal was measured. It was found that CexTb1-xP5O14: Mn belongs to monoclinic system, space group P21/c. The lattice parameters have been calculated, EPR data showed that the manganese. ion has a valency of two in CexTb1-xP5O14: Mn. The spectra showed an energy transfer from Ce3+ to Mn2+, and Tb3+ in CexTb1-xP5O14: Mn. The emission peaks of Mn2+ and Tb3+ are overlaped and the peak of Tb3+ is increaced.

Key words: Crystal growth, Pentaphosphate, Spectra of Ce3+ Tb3+ and Mn2+, Crystal structure
