Abstract: | (Ca1 − x, Srx)Al2Si2O8:0.06Ce3+, M+ (M+ = Li+, Na+, K+) phosphors have been prepared by conventional solid-state reaction method. The structural and optical properties of the phosphors were characterized by X-ray diffraction (XRD) technique and spectrophotometer, respectively. A regular variation was found among the XRD patterns of (Ca1 − x, Srx)Al2Si2O8:0.06Ce3+ phosphors based on the changing of Sr content. With the increase of Sr content, the maximum of emission band presented slight blue shifts (~ 15 nm). The luminescence intensity of CaAl2Si2O8:0.06Ce3+ and SrAl2Si2O8:0.06Ce3+ were significantly enhanced when K+ and Li+ were incorporated, respectively. |
