A series of Ce 3+ , Mn 2+ codoped Ba x Sr y Li z SiO 4 :Ce 3+ , Mn 2+ phosphors were synthesized by partially liquid-phase method. The effects of Ba/Sr ratio, Ce/Mn ratio and lithium content on the emission spectra of the Ba x Sr y Li z SiO 4 :Ce 3+ ,Mn 2+ (BSLS:Ce,Mn) phosphors were investigated in details, which showed blue emission around 410nm wavelength and red emission at about 620nm wavelength, respectively. With the increasing of Sr/Ba ratio, the color of BSLS:Ce, Mn was changed from
