Abstract: The present invention provides an oxide glass capable of exhibiting a long lasting afterglow and photostimulated phosphorescence, whereby energy can be accumulated by radiation excitation, for example, by gamma -rays, X-rays and UV-rays, light emission can be continued for a long time even after stopping the excitation. Furthermore, the long lasting afterglow and photostimulated luminescence oxide glass capable of exhibiting photostimulated luminescence by irradiation of infrared rays or visible rays can be used not only as a material for confirming an infrared laser or controlling an optical axis, but also as a material for recording or reproducing of gamma -ray, X-ray or UV-ray images and further can be used as an optical recording material of a type that can be read. This glass material is represented, in term of atoms making up the glass, by the following chemical composition (mol %):
