It is through an alloy-nitridation method at \u223c2173 K in nitrogen atmosphere, with stable alloys (CaAl, SiEu), AlN, and \u03b1-Si3N4 powders as starting materials. A linear relationship between the lattice parameters and m values of (Ca0.995Eu0.005)m\/2Si12\u2212mAlmN16 compositions is obtained, indicating that our samples contain very little oxygen, i.e. herein so-called Eu-doped pure-nitride \u03b1-sialons. The (Ca0.995Eu0.005)m\/2Si12\u2212mAlmN16 compounds with 2.4\u2264m\u22644.0 give the strongest emission. The emission shifts to longer wavelength with m values increasing as well as Eu contents increasing. (Ca0.995Eu0.005)m\/2Si12\u2212mAlmN16 compositions with smaller m values exhibit better thermal quenching properties.<\/p>","protected":false},"excerpt":{"rendered":"<p>J.
