Abstract

Eu doped CaAlSiN3 phosphor was successfully prepared by high-temperature solid phase method using Ca₂Si₅N₈:Eu as major raw materials. The phase transition and luminescence properties were studied in detail. It is found that the phase changes from Ca₂Si₅N₈ to CaSiN₂ when the temperature reaches 800 ℃. Then CaAlSiN₃:Eu phosphor was synthesized by the solid phase reaction: (Ca,Eu)SiN₂+AlN→(Ca,Eu)AlSiN₃ when the reaches 1500 ℃. The morphology and luminescence properties of CaAlSiN₃: Eu with different Eu concentration was also studied.
