Abstract:

 Germanium (Ge) nanoparticles (NPs) are synthesized by means ofpulsed laser (Nd-Yag) ablation of bulk germanium target immersed in ethanolwith nanosecond laser pulses at fixed pulse energy at wavelength (532 nm).The fabricated nanoparticles are characterized by employing differentdiagnostics such as UV-Vissible absorption spectroscopy, atomic forcemicroscopy.The results of preparation and optical characterization of the Genanoparticle suspensions are presented. The considerable shift of the band gapenergy of the nanoparticles compared to the bulk semiconductors wasobserved, and the estimated optical gap was about 3.75eV.
