摘要:
The present invention belongs to the technical field of inorganic luminescent materials, particularly relates to a nitride fluorescent material, and further discloses a light-emitting device containing such a fluorescent material. The nitride fluorescent material contains a compound with a structure like MmAlxSiyN3: aR, bEu, cCe. The fluorescent material has very high physical stability and chemical stability, and the fluorescent material is better in crystallization, and thus has relatively high external quantum efficiency. When being applied to a light-emitting device, the fluorescent material can fully exert the advantages of good stability and high external quantum efficiency, and the light-emitting efficiency and stability of the light-emitting device can be further improved.
