✦ Synopsis
A new fluorescent glass with Eu and Ce has been synthesized and characterized. Absorption, excitation, and emission spectra of Eu 3؉ have been measured. The effect of Ce-coactivation on fluorescence was also investigated. Sustained irradiation by ultraviolet light leads to a persistent extinction of fluorescence. This result is discussed in terms of photoionization of Ce 3؉ . Fluorescent photosensitive glass make it possible to print fluorescent photographic images within glass samples.
