β -SiAlON and method for producing the same and light emitting device |
| abstract |
β -SiAlON into which Eu is dissolved as a solid state is represented by a general formula: Si6-zAlzOzN8-z. The spin density is 6.0*10<SP>16</SP> per gram or less with respect to the absorption of g=2.00 ± 0.02 at 25 DEG C obtained by the electron spin resonance method. The method for producing β -SiAlON comprises a mixing process for mixing the raw materials; a sintering process for sintering the mixed raw materials to β -SiAlON; a heating process that the temperature rises from 1500 DEG C to the sintering temperature at a rate of 2 DEG C/min or less when the environment temperature of the mixed raw materials without being sintered rises to the sintering temperature; an annealing process for annealing the sintered β -SiAlON; and an acid treatment process for acid-treating the annealed β -SiAlON. This invention enables to provide β -SiAlON with high light emitting efficiency, the method for producing β -SiAlON and the light emitting device. |
