All the glasses which contain the MPs exhibit a green–bluepersistent emission after stopping the UV irradiation (Fig. 1).The persistent luminescence intensity depends on both the MPconcentration and the glass matrix. The green emission fromthe samples clearly indicates that it is possible to prepare aphosphate-based glass which contains Sr4Al14O25:Eu2+,Dy3+MPs using a one-step melting process in normal atmosphere.Our glasses exhibit a relatively long emission duration as thegreen luminescence of our glass could still be seen after 35 min.
