Title: Influence of external magnetic field on laser-induced gold nanoparticles fragmentation

Abstract

Laser-assisted fragmentation is an efficient method of the nanoparticles size and morphology control. However, its exact mechanisms are still under consideration. One of the remaining problems is the plasma formation, inevitably occurring upon the high intensity laser irradiation. In this Letter, the role of the laser-induced plasma is studied via introduction of high-intensity external magnetic field (up to 7.5 T). Its presence is found to cause the plasma emission to start earlier regarding to a laser pulse, also increasing the plume luminosity. Under these conditions, the acceleration of nanoparticles fragmentation down to a few nanometers is observed. Laser-induced plasma interaction with magnetic field and consequent energy transfer from plasma to nanoparticles are discussed.

  • Thionicotinamide-capped gold nanoparticles undergo fusion as well as fragmentation upon laser pulse excitation (532 nm). The aggregation effect which is induced by thionicotinamide also disappears following laser pulse excitation. The morphological changes induced by thermal and photochemical effects were found to influence the optical properties of these particles.
  • Studies of fragmentation process of gold nanoparticles (Nps) in deionized water after generation by femtosecond laser ablation were performed. To analyze the fragmentation process, direct IR ultrafast pulses or super-continuum (SC) radiation focused in the colloidal solution were used in separate steps. IR pulses and SC generated externally in a sapphire crystal or directly inside the water were applied under low fluence regime. In the latter cases, to evaluate the effect on fragmentation of the different spectral bands present in the SC, we have determined different efficiency regions characterized by means of the product between the spectral response and themore » optical extinction spectrum corresponding to the initial Nps solution. From the analysis of this product function, we can conclude that the main fragmentation mechanism is due to linear absorption in the visible region. Likewise, the SC generated in water resulted more efficient than the SC obtained externally by a sapphire crystal. This fact may be attributed to the blue broadening of the water SC spectrum (as compared with the sapphire SC) due to the large intensity used for its generation. Transmission electron microscopy and small angle x-ray scattering measurements support the results found from optical extinction spectroscopy.« less
  • The paper presents results of formation of expanding plasma by combining laser-produced plasma with an external strong magnetic field. The plasma was generated by means of a Nd-glass laser which was focused on a solid target located on the axis of a single-turn coil providing magnetic field of up to 50 T. Spatial characteristics of the dynamics of interaction of the plasma with the magnetic field were registered by means of a three-frame interferometry. For registration and analysis of interferograms, CCD cameras and a multichannel image acquisition system were used. An interesting influence of the strong magnetic field on themore » plasma dynamics and shape was observed. Preliminary results of numerical modelling are compared with the experimental data. {copyright} {ital 1996 American Institute of Physics.}« less
  • A femtosecond laser-based method to control the size characteristics of gold colloidal nanoparticles is reported. The method uses the supercontinuum generation produced through a strong nonlinear-optical interaction of the femtosecond radiation with a liquid to fragment relatively large colloids and reduce their agglomeration. The fragmented species then recoalesce to form smaller, less dispersed, and much more stable nanoparticles in the solution. The size of the nanoparticles after the treatment is independent of the initial characteristics of colloids, but depends strongly on laser parameters and on the presence of chemically active species in the solution.
  • A model SiO2 thin-film system containing gold nanoparticles serving as nanoscale absorbing defects is investigated with the goal of unraveling the connection between 351-nm pulsed-laser energy absorption process inside a single defect and the resulting film damage morphology. For this purpose, gold nanoparticles are lodged at a well-defined depth inside a SiO2 monolayer film. Particle sites, as well as nanoscale craters generated at these locations after 351-nm irradiation, are mapped by means of atomic force microscopy. The results of this mapping confirm a damage mechanism that involves initiation in the nanoscale defect followed by absorption spreading out to the surroundingmore » matrix. At low laser fluences (below optiexecy detected damage onset), the probability of crater formation and the amount of the material vaporized is, to within {approx}25% of the average value, almost independent of the particle size. Inhomogeneities in the particle environment are held responsible for variances in the laser-energy absorption process and, consequently, for the observed particle/crater correlation behavior. Investigation of damage threshold as a function of particle size (2-nm to 19-nm range) showed that even few-nanometer-diameter particles can lead to a significant threshold reduction. The ''nanoscale'' damage threshold is introduced as a laser fluence causing localized melting without significant vaporization.« less
