Abstract: In general, carbon nanoparticles (CNPs) have different applications in the environment [1], energy [2], biomedical [3], and the other fields of science. There are quite intensive diversity of techniques which could be applied to produce nanoparticles. In this work, carbon nanoparticles were produced using laser ablation in liquid (LAL) medium in one-step producer. In this method, first the activated carbon (AC) was dispersed into deionized water and irradiated via a Fiber laser with a wavelength of 1064 nm. The UV-visible spectroscopy was done to investigate the optical properties of product. Also, SEM and EDAX were used to examine the morphology and atomic percentage of elements, respectively.
