摘要：

Silicon and germanium nanoparticles were synthesized by laser ablation of solid Si and Ge targets in ethanol. The targets were immersed in a vessel containing the solvent and irradiated during 1 min at a fluence of 0.86 J cm(-2). The obtained colloidal nanoparticles were structurally characterized by Raman spectroscopy and Transmission Electron Microscopy, where nanocrystals ranging from 5 to 20 nm were found. The optical absorption of the samples was studied by UV-vis spectroscopy. Results showed a band gap widening for both semiconductor nanocrystals.
