摘要：
The Eu2+ activated CaAlSiN3 phosphor was synthesized by solid- state reaction method under a nitrogen atmosphere at 1550 degrees C for 6h. The phosphors structure was measured by X-ray diffraction (XRD); excitation spectra, emission spectra and decay lifetime were obtained by fluorescence spectrophotometer equipped. It showed a broad excitation band originating from the 4f7-4f65d transition of Eu2+ ion extending to 650nm and the peaking at 467nm; a strong emission band centering at 668nm, and the lifetime of Eu2+ in the CaAlSiN3 host is 1.4227 mu s.
