“…UV-visible spectrum of synthesized carbon nanoparticles without doping indicates absorption peak at about 228 nm. This may be contributed the ππ* transition typically found in the carbon which is in a range of 180 -280 nm [14]. It is of the aromatic sp 2 domains, and leads to very low fluorescence intensity [2].…”

“…The main advantage of using PLAL is that it does not require vacuum equipment for the NPs fabrication, hence, it is a low cost and a simple technique. Moreover, after the particles' fabrication by this method they are easily collected [9]. The properties of nanomaterials synthesized by the laser ablation of solids in liquids depend on two factors: firstly, the laser parameters such as the wavelength, pulse energy, exposure duration and the laser repetition rate.…”

Pulsed Laser Ablation in liquid (PLAL) is considered as a robust and simple technique for producing nanoparticles (NPs) using lasers. The carbon-based nanoparticles were fabricated via the PLAL approach by irradiating a graphite target with a pulsed Nd:YAG laser of wavelength 532 nm. The graphite target was immersed in distilled water and irradiated for 10 min. The pulse length, reputation rate, and fluence were 6 ns, 10 Hz, and 0.4 J cm −2 , respectively. The structural and physical properties of the synthesized NPs were investigated and analyzed using different characterization methods. For example, Transmission Electron Microscopy (TEM) images revealed diverse carbon nanostructures such as graphene nanosheets, nanospheres, nanospheres in the shape of a necklace, and nanotubes. The spectrum of Energy Dispersive X-Ray spectroscopy (EDX) confirmed successful synthesis of high purity carbon nanostructures. Moreover, the result of X-Ray Diffraction (XRD) Spectroscopy indicated the presence of reduced Graphene Oxide (rGO) with a (002) plane and the absence of Graphene Oxide (GO). The transmission spectrum from Ultraviolet-Visible (UV-vis) analysis showed a strong trough at 266 nm which is attributed to the presence of carbon nanostructures. Furthermore, Fourier-Transform Infrared Spectroscopy (FTIR) analysis demonstrated the vibration bonds related to carbon. The nanostructures produced were semi-stable with little agglomeration as was inferred from the results of the Zeta Potential. Finally, the Dynamic Light Scattering (DLS) analysis supported the TEM results. PLAL technique is proved to be a simple method for producing carbon-based nanomaterials. Moreover, the laser fluence was found to be an important factor which affects greatly the type of nanostructures that could be synthesized during laser ablation.

“…Some other structures like carbon nitride nanocrystals in liquid ammonia [21] and onion-like carbon-encapsuled cobalt carbide core/shell nanoparticles in acetone [22] have also been obtained using nanosecond laser pulses. The LASL technique has been likewise reported to be an efficient technique to produce graphene in liquid nitrogen [23] or for the obtaining of dispersed in ethanol carbon nanoparticles with blue-green PL emission [24] or dimethyformamide [25]. Carbon dot-like nanoparticles suspended in deionized water have been also obtained through this technique using an UV laser for its production.…”
