Abstract
The synthesis and application of metal and ceramic nanoparticle are significant subject in science and engineering. The Copper nanoparticles has more application in material science, Nano medicine and electronic. One of the green method for the production of nanoparticles pulsed laser ablation PLAL that has become increasingly popular. The effect of the nature of the surrounding liquid medium on the size, shape and optical absorption of synthesized nanoparticles prepared by laser ablation of pure copper in different liquids is investigated. The liquid media surrounding the target is thus an important factor affecting the shape, mean size, size distribution and composition of the particles. With the help of Nd: YAG laser with maximum 15mJ energy, pulse duration 10ns and wavelength 1064nm. The ablation of copper target was carried out in distilled water, Ethylene Glycol and Ethyl Alcohol medium, leading to formation of copper and copper oxide nanoparticles of various sizes and shapes. Transmission Electron Spectroscopy TEM, UV-Vis Spectroscopy and Fourier Transform Infrared (FTIR) Spectroscopy were employed for characterization of the particle size, shape and optical properties, respectively. We also compared the synthesized copper nanoparticles in terms of size and stability.
