ILLUMINATION SYSTEM COMPRISING A RADIATION SOURCE AND A FLUORESCENT MATERIAL |
摘要 |
The invention concerns an illumination system for generation of colored, especially amber or red light, comprising a radiation source and a fluorescent material 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 a amber to red emitting a rare earth metal-activated oxonitridoalumosilicate of general formula (Ca1−x−y−zSrxBayMgz)1−n(Al1−a+bBa)Si1−bN3−bOb:REn, wherein 0≦̸x≦̸1, 0≦̸y≦̸1, 0≦̸z≦̸1, 0≦̸a≦̸1, 0<b≦̸1 and 0.002≦̸n≦̸0.2 and RE is selected from europium(II) and cerium(III). |
