“…The machine has a 16-micron layer accuracy and 14 photopolymers to simulate a range of material characteristics and create 3D models. The use of flow-cell limits occluding of the surface from the beam by the ablated material (due to the produced particles being moved by the flow) [16,17,40]. The process parameters of the laser power, stage height, laser beam scan speed, raster pattern and laser repetition rate were controlled using the National Instruments LabVIEW programme.…”

“…To the best of our knowledge, studies in this area are limited. Al-Douri et al [187] conducted a study by ablating GaN plates immersed in distilled water with nanosecond pulses and synthesised GaN colloidal NPs with variance in the fluence range from 380 to 1500 J/cm 2 . They observed that the mean size and productivity of the NPs increase with laser fluence because a rise in the laser absorptivity has a considerable effect on the particle size.…”

Influence of Laser Process Parameters, Liquid Medium, and External Field on the Synthesis of Colloidal Metal Nanoparticles Using Pulsed Laser Ablation in Liquid: A Review

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.

“…This method provides the advantage of ease of manipulation of reaction parameters to produce nanomaterials with various morphologies, sizes, and phases. [10,11,12] Douri et al offer pulsed laser ablation process, a new method of synthesis which is employed in aqueous solution. [10,11] It is quite different from the chemical method of synthesis where an organic liquid is used as the reaction medium.…”

Colloidal Synthesis of Zirconium Disulphide Nanostructures and their Stability Against Oxidation

The need to exploit the exotic properties of ZrS2 synthesized via colloidal means is imperative. For almost a decade now there has been no literature on the colloidal synthesis of ZrS2 nanomaterials. Meanwhile, several publications are available on other methods of synthesis mostly chemical vapour transport (CVT) and chemical vapour deposition (CVD). The synthesized bulk material from the CVT method is further subjected to exfoliation (mechanical or liquid) to obtain mono or few‐layers of ZrS2. With the colloidal method, there is a possibility of the oxide being formed during the synthesis of ZrS2 and likely destabilization of the nanomaterial after synthesis on exposure to ambient environment. In this study, both the heat up and hot injection methods were employed to fabricate various morphologies of ZrS2 nanomaterials. The metal and sulphur precursors were dissolved in a mixture of octadecene (ODE) and oleic acid (OA); and refluxed at a temperature of 290 °C in the presence of nitrogen gas. ODE served the role of non‐coordinating solvent, while OA served as the capping agent. Nanorods, nanospheres and nanosheets were obtained from the heat up method. Meanwhile, the hot injection approach produced nanosheets and nanospheres with well noticeable hollow centres. Powder X‐ray diffractometer (PXRD) validated the formation of the ZrS2 hexagonal phase with traces of oxides of zirconium, ZrO2. The peak of S2p was conspicuously absent while the Zr3d peak was well noticeable in the XPS spectra. XPS and EDS measurements confirmed the replacement of the sulphur atom by the O atom on the surface of the nanomaterials. Only one exciton peak was observed for the absorption spectra from both the heat up and hot injection methods; and thermal thermogravimetry analysis (TGA) revealed three plateaux of decomposition of the nanomaterials.
