Abstract
Si nanoparticles and nanowires have been synthesized on Si substrates by pulsed laser ablation (PLA). The Si nanowires which have a crystalline core with an amorphous shell have been grown on the Si nanoparticles with increase of the ablation time. The obvious blue shift has been observed from the photoluminescence (PL) spectrum.
