Silicon nanocrystals have raised hopes in applications for Si-based devices. Our interest is synthesis of Si/SiO2 nanoparticles having dimensions < 10 nm, with the final goal "Quantum Dots" for specific application in biology, micro and nanoelectronics. We present the studies of nanometric silicon powders produced by laser ablation. The effects of laser wavelength, fluence, and gas pressure, on the nanoparticle structure and size distribution have been investigated by transmission electron microscopy.
