Luminescence nanocrystals or quantum dots give grate potential for bio-analysis as well as optoelectronics. Here we report an effective and non-expensive fabrication method of silicon carbide nanocrystals, with diameter below 10 nm, based on electroless wet chemical etching. Our samples show strong violet-blue emission in the 410-450 nm region depending on the used solvents and particle size. Raman and infrared measurements suggest the varied nature of surfaces of silicon carbide nanocrystals which elucidate the behavior of the silicon carbide colloid solvents and also give opportunity to modify the surface easily for specific biological, medical or other application.
