In this paper,we report a new route to syntheses of a series of pure luminescent materials of rare earth phosphates with crystalline phase,microcrystalline glass and glass using microwave method under the condition of appearance microwave power at 20%～70% level(100% power is equal to 650 W of microwave energy, adjusting at 10 level) and reaction time at 7～10 min.The molar ratio of Re2O3 and P2O5 plays an important role for the formation of the luminescent materials of crystalline phase,micro-crystalline glass and glass.The crystal structures were characterized by X-ray diffraction.The infrared spectra of these luminescent materials formed under microwave condition showed that the NO,NH and H2O species in the starting mixture were completely removed,giving pure luminescent materials for crystalline phase,micro-crystalline glass and glass.The luminescent properties were investigated by fluorescence emission and excitation spectra.The experiment results show that the V ion in the substrate is sensitive to Eu3+,Dy3+,Sm3+,Tb3+ increasing the luminescent intensity,for example,the emission intensity of the sample Y0.95(V0.03, P0.97)O4:Eu(0.05)is 80 times more than that of the sample without V ion.
