A novel red phosphor Eu3＋ doped magnesium titanate （MgTiO3） was synthesized via sol-gel method. The X-ray diffraction patterns （XRD） revealed that a pure MgTiO3 phase was obtained. Its excitation spectrum consisted of a broad band （〈350nm） and a series of narrow bands in the long wavelength, and the strongest excitation peak at 465nm might be exited by GaN-chip to emit red light for white LED. The phosphors showed strong emission at 614nm which could be attributed to the 5D0→7F2 emission of Eu3＋ . The emission intensity of MgTiO3：Eu3＋ phosphor reached the maximum at the Eu3＋ concentration of 3.5mol.%. The luminescent properties （such as emission intensity and decay times） were further improved by introducing Al3＋ as a charge compensator, demonstrating potential applications in white LED.
