Preparation of Nickel Nanoparticles via Laser Ablation in Liquid and Simultaneously Spectroscopy
Nickel nanoparticles were prepared via Nd:YAG pulsed laser in methanol. Nanoparticles morphology have been studied by transmission electron microscope (TEM). X-ray diffraction was carried out to study the structure of laser generated nanoparticles. The optical properties of nanoparticles in liquid were investigated through UV-Vis spectroscopy. The magnetic property of Ni was studied with vibrating sample magnetometer (VSM). The information about the laser ablation conditions could be deduced from the plasma, created during the material removal due to the very fast expansion of metallic vapours.
