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.

A method for manufacturing a solid element device, which comprises providing a glass-containing Al2O3 substrate (3) having a GaN based LED element (2) placed thereon, setting a P2O5-ZnO based low melting point glass in parallel with the substrate, and carrying out a press working at a temperature of 415 DEG C or higher under a pressure of 60 kgf in a nitrogen atmosphere. Under these conditions, the low melting point glass has a viscosity of 10 poise, and is adhered via an oxide formed on the surface of the glass-containing Al2O3 substrate (3). A solid element device manufactured by the above method can be manufactured through a glass sealing working at a low temperature and also has a highly reliable sealing structure.
