Size properties of colloidal nanoparticles produced by nanosecond pulsed laser ablation and studying the effects of liquid medium and laser fluence

Picosecond laser induced fragmentation of coarse Cu2O particles into nanoparticles in liquid media

“…This is due to the difference in physical, optical and chemical properties of ethanol and water [14,15]. Based on the above presented morphological and crystallinity data of the fragmented Cu 2 O particles and the available literature about the fragmentation mechanism of semiconducting particles [16][17][18][19][20], the following fragmentation mechanism for Cu 2 O is proposed.…”

Synthesis of surfactant free stable nanofluids based on barium hexaferrite by pulsed laser ablation in liquid

“…The expansion of plasma plume is affected by the density and viscosity of liquid environment. 15 The higher opposing force caused by higher viscosity of the solvent results in difference in the expansion dynamics of the plume which in turn exert inuence on the homogeneity of the plume. 29 Nanoparticle characteristics are affected by target material properties also.…”

“…5 The thermodynamic and optical properties of liquid medium also determine the different parameters of plasma and cavitation bubble. 15 The pressure and temperature of plasma plume and the decay process of its temperature and pressure are also inuenced by the different properties of the solvent used. 16 Solvent properties such as viscosity, refractive index and dipole moment play an important role in the life time of cavitation bubble which in turn affects the morphology of nanoparticles.…”

Synthesis and Characterization of Aluminum Nanoparticles Prepared in Vinegar Using a Pulsed Laser Ablation Technique

“…However, the nanomaterials obtained through this method depend greatly on the used liquid medium [8,9], laser wavelength [10], laser energy [11][12][13], and irradiation time [8] along with other parameters. Applying the first harmonic wavelength of a Nd:YAG laser (λ = 1064 nm), irradiated aluminum targets immersed in ethanol, acetone, or ethylene glycol resulted in Al nanoparticles with different diameters ranging between 30 and 100 nm [8,9]. It was noticed that finer particles (mean diameter of 30 nm) were obtained in acetone [8] or ethanol [9], when longer ablation durations are applied [8].…”

Likewise, irradiated aluminum targets in dry tetrahydrofuran (with or without the addition of oleic acid) resulted in Al nanoparticles with an average size of 21 nm [14].…”
