Luminescence properties of CdSiO3: Mn2+, RE3+ (RE = Sm, Dy, Eu) phosphors

CdSiO3: Mn2+, RE3+ (RE = Sm, Dy, Eu) long-lasting phosphors were prepared by the conventional high temperature solid-state method. The results of XRD measurement indicated that the products calcined at 1050 °C for 3 h had a good crystallization without any detectable amount of impurity phase. From photoluminescence (PL) spectra and the afterglow intensity decay curves, rare-earth ions co-doped CdSiO3: Mn2+ phosphors possessed better luminescence properties than Mn2+ doped ones. Role of Eu3+ co-doped into CdSiO3: Mn2+ matrix was discussed in this paper.
