| Abstract | ||
| Germanium (Ge) nanoparticles (NPs) are synthesized by means of pulsed laser (Nd-Yag) ablation of bulk germanium target immersed in ethanol with nanosecond laser pulses at fixed pulse energy at wavelength (532 nm). The fabricated nanoparticles are characterized by employing different diagnostics such as UV-Vissible absorption spectroscopy, atomic force microscopy. The results of preparation and optical characterization of the Ge nanoparticle suspensions are presented. The considerable shift of the band gap energy of the nanoparticles compared to the bulk semiconductors was observed, and the estimated optical gap was about 3.75eV | ||
