Název v původním jazyce

Distribution mapping of metal-based nanoparticles by Laser-Induced Breakdown Spectroscopy

Popis výsledku v původním jazyce

Distribution mapping of nanoparticles (NPs) and quantum dots (QDs) using LIBS was optimized in order to achieve best spatial resolution and lowest detection limits. The dependence of the LIBS signal intensity on the volume and concentration of the injected NPs onto different substrates was investigated in detail. Modified ablation system New Wave UP-266 MACRO with Nd:YAG laser operating at 4th harmonic wavelength of 266 nm was equipped with chromatographic paper or polystyrene microplates holder. Software-controlled movement in x,y direction enabled scanning of the sample surface. In double pulse orthogonal configuration the second re-heating laser pulse with fundamental wavelength of 1064 nm (Quantel, Brilliant) was delivered to the primary plasma plume using two mirrors in the periscope arrangement allowing precise laser beam positioning. Samples were measured in the air at atmospheric pressure.
