Abstract
A series of Ce3+, Mn2+ codoped BaxSryLizSiO4:Ce3+, Mn2+ 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 BaxSryLizSiO4:Ce3+, Mn2+ (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 orange to red. However, the intensity of blue emission was reduced and red emission was enhanced with an incensement of Mn/Ce ratio. The strongest intensity of emission for the phosphor was obtained at Li content of 15 mol%.
