摘要：

Photo- and X-ray induced luminescence properties of Sn2+-doped zinc phosphate glasses with different chemical compositions were investigated. Decay constants of the glasses decrease with increasing the ZnO amount, which are independent of excitation light sources. By comparison of emission properties, we have found that the glass structure affects both luminescence properties. The broader emission band in the P2O5-rich glasses suggests that the site variation of Sn2+ centers is mainly due to the P2O5 sub-networks. It is expected that the P2O5 sub-networks are effective for not only photoluminescence but also the X-ray induced radio-luminescence and storage luminescence. (C) 2017 Elsevier Ltd.
