抄録

The optical absorption band at 5.0 eV (the 'B2 band') is classified into two types (B2α: and B2β), each having different photoluminescence peak, half width, and decreasing characteristic by heat treatment. The 7.6 eV absorption band is found in samples with the B2α band. The 7.6 eV and the B2α bands are caused by the same oxygen vacancy in the form of {triple bond, long}Si-Si{triple bond, long}. The former band is due to a singlet-to-singlet transition, while the latter to a singlet-totriplet transition.
