摘要：

Novel pink light emitting long-lasting afterglow CdSiO3:SM3+ phosphors are prepared by the conventional high-temperature solid-state method and their luminescent properties are investigated. XRD and photolurflinescence (PL) spectra are used to characterize the synthesized phosphors. The phosphors are well crystallized by calcinations at 1050degreesC for 5 h. These phosphors emit pink light and show long-lasting phosphorescence after they are excited with 254 nm ultraviolet light. The phosphorescence lasts for nearly 5 h in the light perception of the dark-adapted human eye (0.32mcd/m(2)). The phosphorescence mechanism is also investigated. All the results indicate that these phosphors have promising potential practical applications. (C) 2003 Elsevier Inc. All rights reserved.
