    摘要: Offered is a fluorescent substance consisting of Eu-activated β-sialon and capable of enhancing the brightness of a light emitting device such as a white LED using blue or ultraviolet light as a light source. The fluorescent substance has as its main constituent a β-sialon represented by the general formula Si6-zAlzOzN8-z and containing Eu, wherein the spin density is 2.0×1017/g or less as measured by electron spin resonance spectroscopy corresponding to an absorption of g=2.00±0.02 at 25° C. In the above fluorescent substance, it is preferable that lattice constant a of the β-sialon be 0.7608-0.7620 nm, the lattice constant c be 0.2908-0.2920 nm, and the Eu content be 0.1-3 mass %.

    摘要: An aerosol of a powder composed of helium carrier gas and particles of a hexagonal aluminum nitride is charged through a transfer pipe 3 into a film deposition chamber 4 whose interior is depressurized by gas evacuation using a vacuum pump 5 to maintain a degree of vacuum of 200-8000 Pa during supply of the carrier gas and the aerosol is blown from a nozzle 6 provided on the end of the transfer pipe 3 inside the film deposition chamber 4 to impinge on a substrate fastened to a substrate holder 7 to make the impact force of the particles at collision with the substrate 4 GPa or greater, thereby transforming the crystal structure of the aluminum nitride from hexagonal to cubic to deposit cubic aluminum nitride on the substrate. As a result, a method of transforming the crystal structure of a Group XIII nitride is provided that enables transformation of a Group XIII nitride to cubic crystal structure using a system of simpler configuration than that used for transforming the crystal structure of a Group XIII nitride by a static pressure application process.
