Abstract: Red phosphor (Li1-aAa)Eu(SiO2)1/6W2O8 and Li (Eu1-bLnb)(SiO2)1/6W2O8(A=Na，K; Ln=La，Y，Gd) particles were prepared by ultrasonic spray pyrolysis. The luminescence characteristics of the particles were investigated with SEM，X-ray diffraction，excitation spectra and emission spectra. The particles were spherical shape，around 1 µm in diameter with narrow size distribution. Aggregation between particles was not observed. The phosphor particles had very high emission intensity. The main excitation peak of the particles was a characteristic intra-configurational 4f-4f emissive transition of Eu3+(7F0→5L6) transition at 396nm. The main peak for the emission spectra was a transition 5D0→7F 2 of Eu3+ at 615nm. Emission intensity of (Li1-aAa)Eu(SiO2)1/6W2O8(A=Na，K) phosphor showed a decreasing trend with increasing radius of ions (Li+
