Abstract

In this paper, the Na2O-PbO-SiO2 system long afterglow luminescent glasses of SrAl2O4: Eu2+, Dy3+ were prepared. XRD analysis indicates the glass samples have the typical diffraction peaks of SrAl2O4: Eu2+, Dy3+. The emission spectra of the luminescent glass shows broad bands peaking at 510nm The excitation spectra of the luminescent glass shows broad bands ranging from 300 to 480nm The afterglow luminescence of the luminescent glasses which are excited by a 40W fluorescence lamp for 30min can be observed in the dark for more 10 hours with the naked eyes
