“…At a pulse wavelength of 532 nm (Figure 5), they observed spherical-shaped NPs adjoined, whereas, at 1064 nm, they observed both spherical and sheet-like structures. In the case of graphene sheets, Solati et al [107] investigated the influence of both laser wavelength and fluence on structural formation. Multilayer sheets were formed at 532 nm, and two layers were formed at 1064 nm.…”

“…However, deciding which parameter plays a decisive role in the resultant formation of the desired NPs remains a challenge. Furthermore, we found studies on PLAL [34,67,72,92,[98][99][100][101][102][103][104][105][106][107][108][109][110][111] that focused on single-parameter evaluation; however, the area of multiparametric analysis of laser parameters on nanoparticle formation can be explored.…”

Pulsed laser ablation in liquid, used for nanoparticle synthesis from solid bulk metal targets (a top-down approach), has been a hot topic of research in the past few decades. It is a highly efficient and ‘green’ fabrication method for producing pure, stable, non-toxic (ligand-free), colloidal nanoparticles, which is often challenging using traditional chemical methods. Due to the short time scale interaction between the laser pulses and the target, it is difficult to achieve complete control on the physical characteristics of metallic nanoparticles. Laser process parameters, liquid environment, and external fields vastly effect the shape and structure of nanoparticles for targeted applications. Past reviews on pulsed laser ablation have focused extensively on synthesising different materials using this technique but little attention has been given to explaining the dependency aspect of the process parameters in fine-tuning the nanoparticle characteristics. In this study, we reviewed the state of the art literature available on this technique, which can help the scientific community develop a comprehensive understanding with special insights into the laser ablation mechanism. We further examined the importance of these process parameters in improving the ablation rate and productivity and analysed the morphology, size distribution, and structure of the obtained nanoparticles. Finally, the challenges faced in nanoparticle research and prospects are presented.

“…Laser wavelength in the PLAL process may have an effect on the produced nanostructures. To investigate the effect of laser wavelength on the production of graphene nanosheets, two wavelengths, 532 nm and 1064 nm, were compared while using liquid nitrogen as the ablation medium [ 90 ]. The wavelength of the laser beam has a great effect on the nature of the ablation process in PLAL, which in turn influences the produced nanostructures.…”

“…It was observed that using 1064 nm as the ablation wavelength of a graphite target resulted in the production of graphene nanosheets. Decreasing the wavelength to 532 nm led to more ablation, which included graphene nanosheets and spherical carbon nanoparticles [ 90 ].…”

“…Two more important points that were investigated are the quality of the produced graphene nanosheets and the role of the wavelength on the quality and thickness of the nanosheets [ 90 ]. The quality of the graphene nanosheets is measured through the ratio of the intensities of the D and G bands (I D /I G ), which indicates the level of disorders.…”

High-quality graphene has demonstrated remarkable mechanical, thermal, electronic, and optical properties. These features have paved the road for the introduction of graphene into numerous applications such as optoelectronics and energy devices, photodegradation, bioimaging, photodetectors, sensors, and biosensors. Due to this, graphene research has accelerated exponentially, with the aim of reaching a sustainable large-scale production process of high-quality graphene that can produce graphene-based technologies at an industrial scale. There exist numerous routes for graphene fabrication; however, pulsed laser ablation in liquids (PLAL) has emerged as a simple, fast, green, and environmentally friendly method as it does not require the use of toxic chemicals. Moreover, it does not involve the use of expensive vacuum chambers or clean rooms. However, the great advantage of PLAL is its ability to control the size, shape, and structure of the produced nanostructures through the choice of laser parameters and liquid used. Consequently, this review will focus on recent research on the synthesis of graphene nanosheets and graphene quantum dots via PLAL and the effect of experimental parameters such as laser wavelength, pulse width, pulse energy, repetition rate, irradiation time, and liquid media on the produced nanostructures. Moreover, it will discuss extended PLAL techniques which incorporate other methods into PLAL. Finally, different applications that utilize nanostructures produced by PLAL will be highlighted. We hope that this review will provide a useful guide for researchers to further develop the PLAL technique and the fabrication of graphene-based materials.
