The luminescence of porous silicon is of great interest for applications in optoelectronic building units. The causes, in particular of the photoluminescence of porous silicon (image from scanning electron microscopy shown here), were only partly understood for a long time. According to the most recent studies, both quantum size effects in nanocrystallites and the luminescence radical states close to the surface play a decisive role.
