“…The maximum plasmon absorbance at 400 nm was obtained using 0.125 mM AgNO 3 solutions, with the formation of spherical AgNP with average diameter of ~11 nm. Above this concentration, the plasmon absorbance was less intense, red-shifted and broader indicating that under these salt concentrations AgNP with larger diameter and a broad size distribution were formed [52].…”

“…In another case, stable suspensions of AgNP were prepared by laser-ablation of a highly pure (99.99 %) silicon (Si) target immersed in aqueous solution of AgNO 3 as silver source [52]. The third-harmonic (λ = 355 nm) beam of a Q-switched Nd:YAG laser was focused on the Si target and the effects of the salt concentration and irradiation time were evaluated.…”

In this chapter, we revise some of the most relevant and widely used synthetic routes available for the preparation of metallic silver nanoparticles. Particular emphasis has been focused in the rationale involved in the formation of the nanostructures, from the early metallic silver atoms formation, passing by atoms nucleation and concluding in the growth of silver nanostructures. We hope the reader will find in this chapter a valuable tool to better understand the relevance of the experimental conditions in the resulting silver nanoparticle size, shape and overall properties.

“…Nanoparticle preparation has been developed through various methods including ultraviolet irradiation photo reduction (Zhou et al 1999), sonoelectrochemical synthesis of nanoparticles (Saez and Mason 2009), microwave-assisted synthesis (Mallikarjuna and Varma 2007), electrocrystallization (Murashova et al 2003), electroless metal deposition (Qiu et al 2005), photo reduction (Yonezawa et al 2005), laser ablation (Brito-Silva et al 2010;Tsuji et al 2008;Jiménez et al 2007). In addition, several chemical and biological procedures have been offered involving: polyol (Sun et al 2003;Zhu and Hu 2004;Gautam et al 2007;Wiley et al 2005), hydrothermal (Zhang et al 2006), template (Adhyapak et al 2004;Sun et al 2005;Hong et al 2001), surfactant self-assembly (Pileni 2003) as chemical methods.…”

Shape-controlled synthesis of silver particles by surfactant self-assembly under ultrasound radiation

et al. 2011

Several methods have been offered for silver nanoparticles production. A new method has been developed including shape-controlled synthesis of silver nanoparticles in different shapes. Dendrite, cubic, spherical and porous structures were formed by self-arrangement of the surfactant as a template under ultrasound radiation. In order to produce silver particles, ascorbic acid has been used to reduce an aqueous solution of silver nitrate in the presence of dodecylbenzenesulfonic acid sodium salt, poly (vinyl pyrrolidinone), and a mixture of organic and aqueous solutions. Scanning electron microscopy and transmission electron microscopy analysis revealed that the morphology and the size of produced particles were influenced by the type of capping agent, presence of ultrasound radiation, and crystallization time. In order to measure the surface roughness of dendrite and porous particles, an optical reflectometer was used. Surfactant molecules in an aqueous solution can aggregate in different shapes depending on temperature, ionic property of solution, time, and aprotic solvent content.

“…There are different pathways for synthesizing nanoparticles (NPs); however, it is a challenge for all of them to improve the control of physical properties of the nanostructures, since their behavior will largely depend on their characteristics (Fojtik et al 1993;Jiménez et al 2004;Pyatenko et al 2004;Popovici et al 2006;Pyatenko et al 2007;Jiménez et al 2008;Cobley et al 2009;Jiménez et al 2010;González-Castillo et al 2015;Ermakov et al 2017). In 2008, Jiménez et al demonstrated a novel hybrid physicalchemical method based on a chemical reaction assisted by laser ablation (Jiménez et al 2008). This is a fast and simple method to synthesize metal-core/dielectric-shell NPs in one step and in an aqueous medium.…”

Assisted laser ablation: silver/gold nanostructures coated with silica

et al. 2017

The synthesis processes of metallic nanoparticles have seen a growing interest in recent years, mainly by the potential applications of the phenomenon of localized surface plasmon resonance associated with metallic nanoparticles. This paper shows a fast method to synthesize silver, gold and silver/gold alloy nanoparticles coated with a porous silica shell by the assisted laser ablation method in three steps. The method involves a redox chemical reaction where the reducing agent is supplied in nanometric form by laser ablation. In the first step, a silicon target immersed in water is ablated for several minutes. Later, AgNO 3 and HAuCl 4 aliquots are added to the solution. The redox reaction between the silver and gold ions and products resulting from ablation process can produce silver, gold or silver/gold alloy nanoparticles coated with a porous silica shell. ratio, on optical and structural properties of the nanostructures was investigated. This work represents a step forward in the study of reaction mechanisms that take place during the synthesis of nanoscale materials by the assisted laser ablation technique.
