Publication date: Available online 5 December 2014 Source: Radiation Measurements Author(s): Tao Wang , Yihua Hu , Li Chen , Xiaojuan Wang , Guifang Ju SrSnO 3 :Sm 3+ persistent phosphor was successfully prepared by high temperature solid-state reaction method. The persistent phosphor was systematically studied by XRD, diffuse reflectance, photoluminescence (PL), persistent luminescence and thermoluminescence (TL) spectra. When irradiated by 254nm ultraviolet light in advance, this phosphor shows a red-orange persistent luminescence dominated at ∼596nm at room temperature. The dependence of Sm 3+ contents on the PL and persistent luminescence properties were investigated. The TL and potential afterglow mechanism of the SrSnO 3 :Sm 3+ phosphor was also discussed in this paper.
