| titleOfInvention | Rare-earth doped nitrogen oxide fluorescent powder and preparation method thereof |
| abstract | The invention discloses rare-earth doped nitrogen oxide fluorescent powder. The chemical composition of the fluorescent powder is Al-xSiyOzN2/3 + 4/3y-2/3z: xEu, wherein the A element is Ca, Ba or Sr. The rare-earth doped nitrogen oxide green fluorescent powder is prepared by using common cheap compounds as raw materials in a mode of adding a fluxing agent during sintering, the brightness and grain appearance are improved by adding the fluxing agent and applying certain air pressure, the nitrogen oxide fluorescent powder with high crystallization purity can be finally obtained, and the nitrogen oxide fluorescent powder with poor luminous performance is prevented from being generated due to incomplete raw material reaction or low crystallinity at a high temperature. |
