Illumination system comprising ceramic luminescence converter |
| abstract |
An illumination system, comprising a radiation source and a monolithic ceramic luminescence converter comprising at least one phosphor capable of absorbing a part of light emitted by the radiation source and emitting light of wavelength different from that of the absorbed light; wherein said at least one phosphor is an europium (II) – activated oxonitridoaluminosilicate of general formula a EA2-zSi5-aAlaN8-bOb:Euz wherein 0 < a < 4, 0 < b < 4 and 0 < z < 0.2; EA is at least one earth alkaline metal chosen from the group of calcium, barium and strontium provides a system with a converter that is effective for conversion of high energy radiation, such as radiation in the UV to blue range of the electromagnetic spectrum. It is also effective, as it is a good transmitter of the light energy, that results from the conversion of the high energy radiation input. Otherwise the light would be absorbed in the material and the overall conversion efficiency suffers. The invention is also concerned with a monolithic ceramic luminescence converter comprising at least one phosphor capable of absorbing a part of light emitted by the radiation source and emitting light of wavelength different from that of the absorbed light; wherein said at least one phosphor is an europium(II) - activated oxonitridoaluminosilicate of general formula EA2-zSi5-aAlaN8-bOb:Euz wherein 0 < a < 4, 0 < b < 4 and 0 < z < 0.2; EA is at least one earth alkaline metal chosen from the group of calcium, barium and strontium. |
