In the last decades, nanotechnology has converged various fields such physical, chemical and biological sciences to bring significant technological advancement. The potential of nanotechnology can be envisaged based on the fact that in the last two decades this technology has touched and revolutionized the research in the fields of electronics, computers, communications, defense, energy and medicine. Nanoparticles, in particular, are a class of nanomaterials which has drawn tremendous interest and advancement in its synthesis (chemical, physical or biological). In this work, a Pulsed laser ablation approach has been developed for the synthesis of ligand-free nanoparticles. Characterization techniques such as optical spectroscopy and Transmission Electron Microscopy (TEM) were combined with Dynamic Light Scattering (DLS) measurements. To further understand this synthesis technique, nanoparticle generation was studied as a function of height of liquid above ablation target. Additionally, systematic investigation was performed to study the effect of irradiation time on nanoparticle yield.
