Patent ID: 7859006

Claim:
A semiconductor light-emitting device member, wherein (A) in a solid state Si-nuclear magnetic resonance spectrum, the semiconductor light-emitting device member comprises at least one peak selected from a group consisting of (a) peaks whose peak top position is in an area of a chemical shift of −40 ppm or more and 0 ppm or less, and whose full width at half maximum is 0.3 ppm or more and 3.0 ppm or less, and (b) peaks whose peak top position is in an area of the chemical shift of −80 ppm or more and less than −40 ppm, and whose full width at half maximum is 0.3 ppm or more and 5.0 ppm or less, (B) silicon content is 20 weight % or more, and (C) silanol content is 0.1 weight % or more and 10 weight % or less.
