Název v původním jazyce

Correlation of Acoustic and Optical Emission Signals Produced at 1064 and 532 nm Laser-induced Breakdown Spectroscopy (LIBS) of Glazed Wall Tiles

Popis výsledku v původním jazyce

An acoustic signal was used for the internal standardization of laser-induced breakdown spectroscopy (LIBS) of a glazed wall tile. For the LIBS analyses, 1064 nm and 532 nm wavelengths of the Nd:YAG laser were utilized. The tile was depth profiled by a single-spot ablation from the glaze into the substrate. Some lines of major elements Si(I) 252.418, Si(I) 252.851, Al(I) 257.509, Cr(I) 295.368, Al(I) 309.271 nm and Ti(II) 334.904 nm were monitored. The decrease in the optical emissions during the ablation was successfully compensated for by normalization to the square power of the acoustic signal in the interval of 290-340 nm. This approach failed for the lines between 250-270 nm. The results were the same for both lasing wavelengths despite differentirradiances. The acquired profiles are in good agreement with the reference X-ray fluorescence measurement.
