In this article, an increase of 1-2 orders magnitude in laser-induced breakdown spectroscopy (LIBS) signals was obtained by depositing silver nanoparticles on metal samples. Nanoparticle-enhanced LIBS (NELIBS) found to be a robust and flexible tool for the chemical analysis metals because sample emission signal did not appear affected much size concentration deposited (NPs) within ranges 10 nm diameter 1 order concentration. On other hand, preliminary NELIBS tests insulators semiconductors...
Although the first nanoseconds to microseconds rule resulting process yield of laser ablation in liquid, a comprehensive view involving combination time-resolved measurement techniques is still lacking. In this paper, fundamental aspects metals water during production nanoparticles are discussed. Three fast diagnostic methods have been applied simultaneously. These Optical Emission Spectroscopy for plasma characterization, shadowgraph and cavitation bubble dynamics scattering mechanisms...
In this paper, nanoparticle enhanced laser-induced breakdown spectroscopy (NELIBS) was applied to the elemental chemical analysis of microdrops solutions with analyte concentration at subppm level. The effect on laser ablation strong local enhancement electromagnetic field allows enhancing optical emission signal up more than 1 order magnitude, enabling LIBS quantify ppb and notably decreasing limit detection (LOD) technique. At optimized conditions, it demonstrated that NELIBS can reach an...
The aim of this paper is the description optical emission spectral features plasma produced by laser–matter interaction, from a fundamental point view. laser induced spectra are discussed in connection with basic mechanisms that take place phase at different time delays pulse. being dynamic system, hierarchy elementary changes continuously because electron number density and temperature decrease during expansion. As consequence this, over duration plasma's persistence prevailing emitting...
In the present work, laser ablation of a graphite target submerged in pure water was tested as methodology for production carbon-based nanoparticles. The effect varying external pressure imposed to liquid investigated first time, range from 1 146 atm. Single or double pulses were used ablate and produced nanoparticles characterized by atomic force microscopy (AFM) Raman spectroscopy. A spectroscopic study induced plasma features carried out with Ti interpreted terms laser-induced cavitation...
In this paper, the new approach for Laser Induced Breakdown Spectroscopy (LIBS) based on nanoparticle deposition sample surface is reviewed from both fundamental and application points of view.
Laser Induced Breakdown Spectroscopy (LIBS) is a fast and multi-elemental analytical technique particularly suitable for the qualitative quantitative analysis of heavy metals in solid samples, including environmental ones. Although LIBS often recognised literature as well-established technique, results about elements chemically complex matrices such soils are quite contrasting. In this work, soil samples various origins have been analyzed by data compared to those obtained Inductively...
