Oxynitride-based phosphor and white light emitting device including the same |
摘要 |
There is provided an oxynitride-based phosphor comprising a β-type Si3N4 crystal structure and represented by a compositional formula of Si6−xAlxOxN8−x:Euy (0<x≦0.3, 0.001≦y≦0.03), the oxynitride-based phosphor having a form of a secondary particle comprising a plurality of primary particles bonded to each other, the plurality of primary particles having pillar shapes. |

1. An oxynitride-based phosphor comprising:
a β-type Si3N4 crystal structure and represented by a compositional formula of Si6−xAlxOxN8−x: Euy (0 <x ≦0.3, 0.001 ≦y ≦0.03), wherein the oxynitride-based phosphor comprises a form of a secondary particle comprising a plurality of primary particles bonded to each other while maintaining shapes of the primary particles, the plurality of primary particles having pillar shapes. |
