GLASS FOR OPTICAL DEVICE COVERING, GLASS-COVERED LIGHT-EMITTING ELEMENT, AND GLASS-COVERED LIGHT-EMITTING DEVICE |
摘要 |
Disclosed is a glass-covered light-emitting element which is covered by a glass having a low glass transition temperature and a thermal expansion coefficient that is only a little different from that of the light-emitting element. Also disclosed is a glass-covered light-emitting device. Specifically disclosed is a glass-covered light-emitting element comprising a semiconductor light-emitting element having a major surface and a P2O5-ZnO-SnO glass covering the major surface of the semiconductor light-emitting element. The glass is essentially composed, in mol % in terms of oxides, of 20-45% of P2O5, 20-50% of ZnO and 20-40% of SnO, and has a glass transition temperature of not less than 290°C but not more than 450°C and a thermal expansion coefficient of not more than 105 OE10-7/°C. |
