Laser-Induced Breakdown Spectroscopy (LIBS) is a very simple but capable spectroscopic analytical method that performs simultaneous multi-element analysis in a single laser shot. By using LIBS, we can identify artificial gemstones that look like real ones. In this study, the samples that are used in...
