A series of red phosphors M3BO6:Eu3+ (M=La, Y) were synthesized at 1150 °C by conventional solid state reaction method and their luminescent properties were investigated. Structural characterization of the luminescent materials was carried out with X-ray powder diffraction (XRD) analysis. Photoluminescence measurements indicated that the La3BO6:Eu3+ phosphor exhibited bright red emission centered at about 612 nm 626 nm under UV excited. La3BO6:Eu3+ phosphor had better luminescent intensity than Y3BO6:Eu3+ phosphors under the same excitation and measuring conditions. It was shown that the 0.08 mol.% Eu3+ ions in La3BO6:Eu3+ phosphors was optimal. The color parameter indicated that La3BO6:Eu3+ phosphor was a preferable red phosphor for white LED.
