γ-LiAlO2:Eu3+(Eu3+:LAO) phosphor was obtained by gel combustion method using LiNO3, Al(NO3)3·9H2O, Eu(NO3)3·6H2O and citric acid as raw materials. The structure, morphology and luminescence were characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM),photoluminescence (PL). The results demonstrated that the phosphor was pure-phase of flaky tetragonal crystal system with a mean size of around 1 μm. The strongest excitation peak was at 254 nm, belonging to the broadband excitation and the maximum emission peak was at 613 nm, corresponding to the 5D0→7F2 transition of Eu3+. Luminous intensity is closely related to the calcination temperature and doping concentration of Eu3+.
