Laser-induced modification of metal nanoparticles formed by laser ablation technique in liquids

Complete Green Synthesis of Gold Nanoparticles using Laser Ablation in Deionized Water Containing Chitosan and Starch

“…Thus, Au nanorods can be synthesized by using potato starch as a stabilizer. Laser-induced particle fragmentation has been reported [11,12,[23][24][25][26]. However, the profound reductions in the particle size and size distribution observed here cannot be attributed simply only to the coupling effects between the ablated particles and the second laser beam that can further heat, melt, and fragment the ablated particles into smaller size particles.…”

EFFECT OF LASER WAVELENGTH AND ABLATION TIME ON PULSED LASER ABLATION SYNTHESIS OF AL NANOPARTICLES IN ETHANOL

“…Horn et al 14 showed that ablation rate of aluminum in noble gas environment increases by increase of the laser wavelength, while Stafe et al 15 have reported against it. There are also contradictions in wavelength effect on size of nanoparticles, as some papers reported increase 17 and some others announced decrease 5,12,16 of the size by increase of the laser wavelength.…”

“…The occurrence of fragmentation mechanism on nanoparticles in higher ablation times and its effect on size reduction was also reported by other researchers 18 . Moreover, fragmentation is sometimes executed under the name of laser irradiation in order to decrease the size of the nanoparticles in colloidal solutions, while usually non-focused beam is radiated and no target is placed in front of it 8,17,21,[25][26][27][28] .…”

“…Effect of laser wavelength on ablation efficiency and size of nanoparticles are not clearly agreed, as there are paradoxes about them 5,12,[14][15][16][17] . Horn et al 14 showed that ablation rate of aluminum in noble gas environment increases by increase of the laser wavelength, while Stafe et al 15 have reported against it.…”

Pulsed-Laser Ablation of Au Foil in Primary Alcohols Influenced by Direct Current

“…Darroudi et al, 2011;Kabashin et al, 2003;Mafune et al, 2002;Šišková et al, 2007, or even DNA (Takeda et al, 2005). In the literature, there have also been published pulsed-laser ablation processes of metallic foils performed in ionic liquids (Wender et al, 2011), or in a wide range of organic solvents, such as chloroform (Compagninni et al, 2002;Mortier et al, 2003;Šišková et al, 2010), toluene (Amendola et al, 2005), tetrahydrofurane (Amendola et al, 2007), dimethylsulfoxide (Amendola et al, 2007), N,N-dimethylformamid (Amendola et al, 2007), acetonitrile (Amendola et al, 2007), acetone (Burakov et al, 2005(Burakov et al, , 2010Boyer et al, 2010;Tarasenko et al, 2005), primary alcohols (Burakov et al, 2010;Compagnini et al, 2002;Simakin et al, 2004;Werner et al, 2008). Another substantial advantage of pulsed-laser ablation process is the possibility to choose (at least in principle) laser wavelength, pulse duration (ns, ps, fs), energy per pulse, and fluence (energy per area).…”
