The behavior of the splitting was different for the different peak, indicating that the symmetries of the associated defects are different. The film after heat treatment at 6 GPa and 1800 degreesC was found to exhibit new luminescence bands approximately 300 and 500 nm. Splitting of the 575 nm peak was recognized to decrease with the heat treatment, suggesting that the residual stress was reduced. (C) 2003 Elsevier Science B.V. All rights reserved.
