摘要：

Photoluminescence (PL) and Fourier transform infrared studies on annealed, spark-processed silicon have been performed. It was found that heat treatments at 600 degrees C and higher temperatures substantially reduce the presence of hydroxyl groups as expected. Nevertheless, the PL of spark-processed Si remains intensive after heat treatments up to at least 900 degrees C. It is therefore concluded that hydroxyl groups (silanol) are not the major cause for PL in spark-processed Si.
