Abstract: In order to enhance the luminescent performance of ZnTiO3:Eu3+（ZTOE）,a series of red-emitting phosphor of ZTOE doped with Li+ was synthesized via sol-gel method.The influence of lattice site occupancy of Li+ on the emission of ZTOE was investigated in detail.The emission intensity was significantly enhanced by introducing different concentrations of Li+ ions.In contrast to lithium-free ZTOE,the red emission intensities（615 nm） of the ZTOE doped with 4 mol% Li+ ions were enhanced by about 2.1 times.Moreover,The chromaticity coordinate of ZnTiO3:Eu3+,Li+（x=0.6717,y=0.3280） has a higher color purity,which is closer to the International Association of Lighting NTSC trichromatic coordinates specified red coordinate（x= 0.670,y= 0.330）.
