“…The Zn 2p peaks are identified at 1021 and 1044 eV corresponding to the doublet of Zn 2p (Zn 2p 3/2 and Zn 2p 1/2 and their exact binding energy values are noted in the figure). These doublets maintained the intensity ratios of 2:1 and the binding energy difference was observed as 23 eV which matches with the reported values of zinc peaks in zinc oxide samples [4] , [10] , [28] . In the case of cobalt high-resolution spectra, according to the increase in Co 2 O 3 concentration, the spectra appeared with lesser noise.…”

“…TiO 2 and ZnO are two well explored metal oxide materials in different applications of material science particularly that of metal oxide semiconductors and optoelectronics. The band gap of these materials is almost similar, ∼3.3 eV [4] , [5] . This wide band gap energy, which is near UV and closer to the end of the blue spectral region enables these materials to be tuned, so that they can absorb the visible photon energy of the solar spectrum.…”

Highlights ZnO:Co 2 O 3 nanocomposites by pulsed laser irradiation in water. Morphology was modified by laser irradiation and Co 2 O 3 content. Elemental composition and their chemical states were confirmed by XPS. Nanocomposites showed higher visible light absorption compared to ZnO. Thin films of the ZnO:Co 2 O 3 nanocomposites showed visible light photocatalysis.

Platinum (Pt) nanoparticles were synthesized by pulsed laser ablation in liquid (PLAL) technique in different liquids (acetone, ethanol, and methanol). Ablation was performed using a Q-switched Nd:YAG laser with output energy of 230 mJ/pulse for 532 nm wavelength. Ablation time and laser energy fluence were varied for all the liquids. Effects of laser energy fluence, ablation time, and nature of the liquid were reported. The mean size, size distributions, shape, elemental composition, and optical properties of Pt nanoparticles synthesized by PLAL were examined by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and UV-Visible absorption spectroscopy.

“…Furthermore, the ablation rate increases with its fluence. Similarly, Zn NPs were synthesised by PLAL in distilled water by Guillen et al [114] at different fluence ranges and water temperatures. They observed different morphologies (elongated and spherical) with varying fluence rates (Figure 8).…”

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.
