摘要：

This paper reports on photoluminescence (PL) and Raman-shift measurements of spark-processed silicon which has been prepared under various conditions. It is observed that spark-processing conducted in a continuous air stream leads to PL spectra whose maxima are shifted substantially into the blue region (i.e., 410 nm) compared to spectra of similar samples prepared in stagnant air or nitrogen. The PL intensity of the blue-luminescing samples was found to be comparable with that of the most efficient, anodically-etched (red-luminescing) porous Si. Possible mechanisms causing the observed PL in spark-processed Si are critically discussed.
