Název v původním jazyce

Improvement of the laser-induced breakdown spectroscopy method sensitivity by combination of ag-nanoparticles and vacuum conditions

Popis výsledku v původním jazyce

Nanoparticles are nowadays used in many different fields. Recent method utilizes the metallic nanoparticles applied on a sample surface to improve the sensitivity of laser-induced breakdown spectroscopy (LIBS) method, so called nanoparticle-enhanced laser-induced breakdown spectroscopy (NE-LIBS). LIBS is atomic emission spectroscopy based method where the laser-induced plasma (LIP) is created by focusing the high energy pulse on a sample surface. LIP emits characteristic radiation corresponding to its elemental composition. To the advantages of this contactless and quasi-destructive method belong fast analysis, measurements of samples in-situ without or with little sample preparation, and simultaneous multi-elemental analysis. Different ambient conditions (vacuum, etc.) affect also the intensity of detected signal. To the limitations of the LIBS method belongs quantitative analysis and low sensitivity in detection of trace elements.
