Effect of Laser Pulse Energy on the Characteristics of Cu Nanoparticles Produced by Laser Ablation Method in Acetone

Annealing-induced highly-conductive and stable Cu–organic composite nanoparticles with hierarchical structures

“…For macro-scale materials, alloying is a simple and standard technique; however, for nanosized materials, to control and retain the precise stoichiometry remains a challenge [11]. The second method is to conduct in situ nanoparticle synthesis by laser ablation [12], reduction of copper salt or oxide [13][14][15] or metal-organic decomposition (MOD) [6,16]. These techniques can produce pure copper nanoparticles in an inert or reductive condition yet still suffer from the oxidation problem during post-synthesis processing.…”

Influence of transverse magnetic field on the properties of laser ablation produced nickel oxide nanoparticles

“…In this case the energy gap between the valence band and the conduction band of the matter will be increased. So the energy gap in nanoparticles is larger than their corresponding bulk matter and with decreasing the size of nanoparticles their bandgap energy gets larger [29].…”

Photoluminescent colloidal Cu@C-NPs suspensions synthesized by LASL

“…Due to its plasmon surface resonance, copper nanoparticles exhibit enhanced nonlinear optical properties, which can result in many applications in optical devices and nonlinear optical materials [11,12]. Due to its potential applications, several routes of synthesis have been implemented for the production of Cu-NPs [11][12][13][14][15][16][17]. Only to cite some of them, it can be referred the chemical reduction of copper sulfate method [11], photochemical synthesis [13], laser ablation in liquids [14][15][16][17], biological routes [18], and among.…”
