Document Type and Number:
Japanese Patent JP6057231
Kind Code:
B2
Abstract:
Provided are an oxynitride phosphor comprising a JEM crystal as a main component and being characterized by light-emitting properties (light emission color or excitation property, light emission spectrum) that is different from the known JEM phosphor, and an application thereof. The phosphor of the present invention comprises the JEM crystal activated with Eu and represented by MAl (Si, Al) 6 (O, N) 10 (where the M element is one or more elements selected from the group consisting of Ca, Sr, Eu, La, Sc, Y, and lanthanoid elements; and includes at least Eu as well as Ca and/or Sr).
