Molecular and atomic emission of fluorine by Laser-Induced Breakdown Spectroscopy using 266, 532 and 1064 nm lasers
Original language description
Several elements as halogens, e.g. fluorine, are difficult to detect by optical emission methods including Laser-Induced Breakdown spectroscopy (LIBS) technique, especially in ambient conditions. Halogens require high excitation energy and the strongest emission lines for halogens are in UV spectral range, where the detection possibility is limited by atmospheric conditions and detection parameters. The emission lines applicable for LIBS analysis are in near IR range (500 nm to 850 nm) with insufficient limits of detection required by many applications1. Molecular LIBS is one of possibilities how to improve the sensitivity for detection of halogens for many years2,3. In this work the CaF molecular bands have been studied in LIBS analysis in respect to the fluorine emission lines in order to achieve higher sensitivity.
