SILICATE PHOSPHORS |
| 摘要 |
The present invention relates to Eu-, Sm- or Pr-doped silicate compounds, to a process for the preparation thereof and to the use thereof as conversion phosphors. The present invention also relates to an emission-converting material comprising at least the conversion phosphor according to the invention and to the use thereof in light sources, in particular pc-LEDs (phosphor converted light emitting devices). The present invention furthermore relates to light sources, in particular pc-LEDs, and lighting units which contain a primary light source and the emission-converting material according to the invention. |

1. Compound of the formula I
(BaySr1-y)Zr1-xHfxSi3O9 (I), where x is in the range from 0 to 1 and, independently thereof, y is in the range from 0 to 1, characterised in that some of the Zr or Hf ions have been replaced by Eu, Pr or Sm ions, where an alkali-metal ion is additionally present if the ions are trivalent. |
