The nanocrystalline Eu3+ doped calcium phosphate was prepared by calcining precursors,which were got by precipitation method combined with ultrasound treatment and some polysaccharide. The existence of Eu3 + inhibited the reaction of Na + ion and SO2-4 radical with apatite and resulted in the transformation of HAP to β- TCP by replacing the calcium ions. The strongest excitation peak was at 393 nm, and other lower peaks were at 361 nm, 375 nm, 381 nm, 418 nm. The strongest emission spectrum appeared at about 618nm.The emission peak (579 nm) showed that Eu3 + ions distributed on Ca2 + sites of the apatitic structure.
