We report a study of the luminescence of SiNCs fabricated by a non-thermal plasma technique. The SiNCs are spherical and exhibit an average size of about 6 nm. They were not luminescent in as-prepared state. In order to reduce their sizes as well as to provide a good oxide surface passivation, they were treated by high-pressure water vapor annealing (HWA). The resulting oxide passivated SiNCs exhibit bright photoluminescence.
