摘要 |
An illumination system comprising a radiation source and a monolithic ceramic luminescence converter comprising a composite material of at least one luminescent compound, and at least one non-luminescent compound, wherein the material of the non-luminescent compound comprises silicon and nitrogen, is advantageously used, when the luminescent compound comprises an rare-earth metal- activated host compound also comprising silicon and nitrogen. Shared chemical characteristics of the luminescent compound and the non-luminescent material improve phase assemblage, thermal and optical behavior. The invention relates also to a composite monolithic ceramic luminescence converter. |
