- Bismuth is a semimetal with rhombohedral crystal structure and anisotropic Fermi surface that have various applications in optics and optoelectronics. In addition bismuth oxide due to the unique physical properties including wide bang gap and high refractive index could be employed in optical coatings, sensors, photovoltaic cells and biological applications. In this research bismuth and bismuth oxide nanoparticles were prepared by pulsed Nd:YAG laser ablation in liquid. Optical properties in visible and ultraviolet wavelengths, crystal structure and nanoparticles size and morphology were investigated by UV-visible spectroscopy, X-ray diffraction and scanning electron microscopy respectively. This research could provide a simple and flexible method for synthesis of pure bismuth and bismuth oxide nanoparticle in a surfactant free liquids
