Abstract: It is the first report of using the microwave heating to synthesize powder crystal form Y2O3: Eu3+phosphors whose structure is a kind of cubic system with lattice parameter a=1.0607 nm,The phosphors have excitation spectra peak atλex=248.5nm,and emission spectra peaks atλex=611.5 nm. Under 254 nm excitation, the phosphors were measured by FMS-1 chromatic detector,and its chromatic coordinates are x=0.646,y=0.350 respectively. The relative luminescent brightness is about 70%,compared with the same standard phosphors.The particle size distribution was measured by SA-CP3 particle size analyzer,and its medium diameter is 3.90μm.

Key words: Microwave heating method, Synthesis, Phosphor, Y2O3:Eu3+
