A series of Ba1?x?1.5ySrxMoO4:ySm3+ red fluorescent materials were synthesized by hydrothermal method and its properties were characterized. The influences of Ba2+ and Sr2+ contents, Sm3+ doping content, reaction temperature and pH value on phase structure, fluorescence properties and micromorphology were studied, respectively. The results showed that the sample of Ba0.843Sr0.15MoO4:0.005Sm3+ has better luminous performance and micromorphology at pH=7 and reaction temperature 130℃. Under 405 nm excitation, the emission spectra of phosphors is composed of three broad bands peaked at 564, 600 and 648 nm, which are resulted from the transition of 4G5/2→6H5/2, 4G5/2→6H7/2, 4G5/2→6H9/2, and the relative intensity of 4G5/2→6H9/2 is more intensive.
