Abstract
Carbon nanoparticles (CNPs) formed by one-step laser ablation in deionized water were carefully studied. Scanning electron microscopy, atomic force microscopy, Raman spectroscopy, and UV–V spectroscopy were used to obtain morphological, chemical, and optical properties of CNPs. SEM outcomes established that the synthesized nanoparticles are semi-spherical with a wide particle size distribution. Raman investigation showed two typical and expected peaks ~ (1300 - 2700) cm−1, which are confirming to transverse and longitudinal modes of the carbon structure. The absorption spectra proved that the intensity of spectra increases as particle size and concentration increase.

Summary
The surrounding conditions of the process of pulsed laser ablation in liquid (PLAL) is an interesting way in the field of the generation of nanoparticles for different materials, such as pure metals, oxides, carbide, iodide, nitride, semiconductors, and nanocomposite materials that can be used. Nanoparticles have a vast interest owing to their unique description contrast to the bulk material; they are used in a very wide range of applications. Among these nanomaterials, carbon-based nanomaterial, including carbon nanotubes and fullerenes, have a high interest because of their excellent properties, such as high ability to let electricity flow, good germ-killing activity, large surface/volume ratio, low poisonous quality, good electron field emission, and biocompatibility [21-30]. We study here the effects of laser energy on the qualities of carbon nanoparticles produced via one-step laser ablation of a graphite target in water
