    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 UPSILON -rays, X-rays and/or UV-rays, and light emission can be continued for a time after the excitation has ceased. Furthermore, the long lasting afterglow and photostimulated luminescence oxide glass can be used not only as a phosphorescent material for nigh illumination or a night signal, but also as a material for confirming an infrared laser or controlling an optical axis, because it exhibits photostimulated luminescence by irradiation of infrared rays or visible rays. In addition, this glass is useful for recording or reproducing UPSILON -rays, X-rays or UV-rays images. The oxide glass has a constitutional composition comprising, at least, silicon (Si), boron (B), zinc (Zn) and oxygen (O), and further containing terbium (Tb) or manganese (Mn) as a phosphorescent agent.

    Abstract: A fluorophosphate fluorescent glass of the present invention, capable of converting invisible ultraviolet rays into visually observable visible rays with high efficiency and available for controlling the optical axis of a laser beam such as an excimer laser has a chemical composition comprising, at least, (I) phosphorus (P), oxygen (0) and fluorine (F), as glass constituting components, and (II) at least one member selected from divalent europium, terbium and (samarium + manganese), as a fluorescent agent, the divalent europium being contained as an essential component and at least one of samarium and manganese being contained as an essential component when terbium is present. In particular, a fluorophosphate fluorescent glass exhibiting a blue fluorescence containing europium as an essential component and a fluorophosphate fluorescent glass exhibiting a white fluorescence containing at least one of samarium and manganese as an essential component are provided.
