Sr-containing α-SiAlON (Srm/2Si12-mnAlm+nOnN16–n:Eu2+) phosphor was obtained as a major phase in compositions having small m and n values, by firing the powder mixture of SrSi2, SrO, α-Si3N4, AlN, and Eu2O3 at 2000°C for 2 h under 1 MPa nitrogen atmosphere. The crystal structure of Sr-α-SiAlON was refined by the Rietveld analysis of the synchrotron X-ray powder diffraction pattern. The crystal structure showed that the Sr–N2 bonding distance of Sr-α-SiAlON was fairly large compared with that of Ca-α-SiAlON. The displacement of N2 sites probably allow the interstices in α-SiAlON to accommodate the introduction of the large Sr ion. Sr-α-SiAlON:Eu2+ phosphor has an excitation wavelength ranging from the ultraviolet region to 500 nm and emits a strong yellow light.
