Laser ablation method: use of surfactants to form the dispersed Ag nanoparticles

Metal-based Inkjet Inks for Printed Electronics

“…Another approach, laser ablation, also enables dispersing the bulk metal in either organic or aqueous medium [46]. This technique was employed for preparation of Ag and Cu NPs in the size range from 4 to 80 nm [23,47,48]. The main disadvantages of gas-phase and laser ablation methods are the difficulties in obtaining uniform and stable NPs.…”

“…Redispersible silver nanopowder as a conductive ink precursor can also be obtained by lyophilization of low concentration dispersion [118,146]. Metal nanopowder precursors prepared by gas-phase [42], laser ablation [23,47,48], and mechanochemical [147,148] methods can also be used for conductive ink formulation. For example, Ag NPs prepared from strips of Ag/Al alloy by leaching of Al with the use of concentrated NaOH solution followed by treatment in an ultrasonic bath [149,150] were used as precursors for solvent-based and water-based conductive inks [151].…”

Photo-induced growth of silver nanoparticles using UV sensitivity of cellulose fibers

“…Silver nanoparticles have been synthesized by either direct evaporation of silver into a liquid medium, such as laser ablation [6][7][8][9], or by reducing silver ions chemically [10][11][12] or through irradiation by electrons [13], ultraviolet (UV) light [14] or Gamma ray [15,16]. To load silver nanoparticles on the surface of fibers, the fibers are usually exposed to a silver nanoparticle sol, resulting in random attachment of nanoparticles on the surface [17][18][19].…”

Femtosecond laser ablation in aqueous solutions: a novel method to synthesize non-toxic metal colloids with controllable size

“…The method consists in the ablation of a target (mostly solid) by an intense laser radiation, yielding to an ejection of its constituents, and to the formation of nanoclusters and nanostructures (for review, see e.g., [1]). In the case of liquid ambience, this process leads to the release of nanoclusters to the environment and the formation of colloidal nanoparticle solution [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In contrast to conventional chemical reduction methods, this method enables us to avoid the use of toxic chemical reduction agents to control the growth of the colloidal nanoparticles.…”
