“…Whereas the shielding of a laser pulse by the self-induced plasma can only be reduced by using shorter pulse lengths, shielding effects induced by previous laser pulses can be reduced procedurally. The strategy is to spatially separate successive laser pulses by adjusting the interplay of the laser spot size, the scanning speed (relative movement between laser beam and target) and the pulse repetition rate to avoid shielding caused by the previous pulse [ 82 , 84 , 90 , 91 , 116 ].…”

Laser synthesis emerges as a suitable technique to produce ligand-free nanoparticles, alloys and functionalized nanomaterials for catalysis, imaging, biomedicine, energy and environmental applications. In the last decade, laser ablation and nanoparticle generation in liquids has proven to be a unique and efficient technique to generate, excite, fragment and conjugate a large variety of nanostructures in a scalable and clean way. In this work, we give an overview on the fundamentals of pulsed laser synthesis of nanocolloids and new information about its scalability towards selected applications. Biomedicine, catalysis and sensing are the application areas mainly discussed in this review, highlighting advantages of laser-synthesized nanoparticles for these types of applications and, once partially resolved, the limitations to the technique for large-scale applications.

“…On the other hand, the higher repetition rate (KHz) increases effective ablation due to the greater heat density it creates on the target [42]. Valverde et al [55] have analyzed the effect of RRLP at 1 to 10 Hz on the synthesis of silver nanoparticles (Ag-NPS) by laser ablation in ethanol. The results showed that the efficiency of silver nanoparticles was decreased by reducing the RRLP from 10 to 1 Hz.…”

This chapter provides an extensive discussion of the pulsed laser ablation in liquid (PLAL) method for synthesizing nanoparticles. It covers the production of various types of nanoparticles, such as metal, semiconductor, and metal-oxide nanoparticles, and the impact of laser parameters on their properties, such as size, shape, composition, and crystallinity. The chapter also delves into the physical and chemical processes involved in PLAL, including nucleation, growth, and coalescence, and how they can be controlled to achieve tailored nanoparticle synthesis. Additionally, it examines the challenges and limitations of PLAL, such as particle aggregation, contamination, and reproducibility, and strategies for improving nanoparticle stability and dispersibility. This chapter is a valuable resource for researchers and scientists in the laser synthesis of nanoparticles, emphasizing the significance of pulsed laser parameters in achieving desired nanoparticle properties.

“…For a PRR of 10 Hz and 15 Hz, the diameter of Zn NPs was 12.1 and 5.6, respectively. Similarly, Alva et al [125] investigated the effects of the laser ablation efficiency by varying the PRR (1-10 Hz) of Ag NPs in ethanol. It was shown that the productivity and ablation efficiency of Ag NPs increased with an increase in the PRR.…”

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.
