A series of red light-emitting phosphors Li2Y4-x(MoO4)7:xEu3+ were synthesized by a sol-gel method. These samples were characterized by DSC-TGA, XRD, PL and FE-SEM analysis. The best dosage of citric acid is four times of metal ions. The optimal sintering temperature is 900°C. The luminescence intensity of Li2Y4-x(MoO4)7:xEu3+ are strongest when the doping concentration of Eu3+ is 4mol. These phosphors...
