Abstract


This paper evaluates the use of Laser Induced Breakdown Spectrosopy (LIBS) for the analysis of Egyptian historical textiles. The chemical information provided by LIBS, as well as the detrimental effects of laser-induced damages were studied as a function of laser energy and the number of laser pulses used for analysis. The main elements in the metal fibers were Cu, Au, Ag, Cr, Mn, Zn and Ca. The results obtained through LIBS were confirmed by Scanning Electron Microscopy coupled to Energy-dispersive X-ray spectroscopy (SEM-EDX). The damage of the metal threads after LIBS application was monitored by SEM and Optical Microscopy. The textile samples used were obtained from the museum of the Faculty of Applied Arts, Helwan University, Egypt.
