Device for providing electromagnetic radiation |
| 摘要 |
Various embodiments may relate to a device for providing electromagnetic radiation, including a radiation assembly for generating excitation radiation, and at least one conversion element for generating conversion radiation, which has at least one first phosphor and which is arranged at a distance to the radiation assembly in a beam path of the excitation radiation. As the first phosphor, a nitridosilicate of the type M2Si5N8:D is used, wherein D=activator and wherein M is selected from the group barium, strontium, calcium alone or in combination, wherein the mean grain size d50 of the phosphor is at least 10 μm. |
