PHOSPHOR CONVERTED LIGHT EMITTING DEVICE |
| 摘要 |
<p>A system includes a radiation source capable of emitting first light and a fluorescent material capable of absorbing the first light and emitting second light having a different wavelength than the first light. The fluorescent material is a phosphor having the formula (Lu 1-x-y-a-b Y x Gd y ) 3 (Al 1-z Ga z ) 5 O 12 :Ce a Pr b wherein
0 < x < 1, 0 < y < 1, 0 <z ‰¤ 0.1, 0 < a ‰¤ 0.2 and 0 < b ‰¤ 0.1. The (Lu 1-x-y-a-b Y x Gd y ) 3 (Al 1-z Ga z ) 5 O 12 :Ce a Pr b is combined with a second fluorescent material capable of emitting third light. The second fluorescent material may be a red-emitting phosphor, such that the combination of first, second, and third light emitted from the system appears white.</p> |
