摘要

CdSiO₃: Mn²⁺, Eu³⁺ long-lasting phosphor was prepared by sol-gel method. The phosphor particles were characterized by the X-ray diffraction (XRD), scanning electron microscopy (SEM) and fluorescence spectrophotometer. The excitation and emission spectra indicated that the particles emitted strong light at 587 nm under around 280 nm excitation. The effects of the calcining temperature and the soaking time on the afterglow properties were studied systematically. Comparing with conventional solid-state synthesis method, the sol-gel method had the advantages such as low energy consumption and homogeneous mixing. In this paper, the decay speed of the afterglow for CdSiO₃: Mn²⁺, Eu³⁺ particles was slower than that obtained by the conventional solid-state synthesis method. In addition, role of Eu³⁺ co-doped into CdSiO₃: Mn²⁺ matrix was also discussed in this paper.
