| Abstract: | The rare earth phosphate powders(Re=La,Ce ,Tb)were synthesized in an aqueous system.The crystal structure and luminescent property of product were investigated by XRD,TEM,PL.The results show that the crystal structure of sample was cubic body center and the particles distributed uniformally.In the ternary system(Ln=La,Ce,Tb),the as-prepared parti- cles showed 543nm green emission resulted which was from terbium ~5D_4-~7F_5 transition. |
