Silica based light emitter, has front-lateral metallic contact, dielectric protective layer, silica substrate and rear side, conductive contact layer

摘要

The silica based light emitter has a front-lateral metallic contact (6), a dielectric protective layer (4), silica substrate (1) and a rear side, conductive contact layer. A thin silica dioxide layer (3) between Silica substrate and dielectric protective layer, produced by local thermal oxidation within an environment formed by a thick Silica dioxide layer, contains europium luminescence centers (5). The electrical connections are provided at metallic contact and rear aluminum layer (8).
