Paper Title:
Compositional Analysis of Polychromes by Laser-Induced Breakdown Spectroscopy
  Abstract

This study deals with the analysis and characterization of wood polychromes by means of Laser-Induced Breakdown Spectroscopy (LIBS). Specimens from a Baroque altarpiece have been analyzed by using a Q-switched Nd:YAG laser source at the wavelength of 355 nm. Previously, a library of characteristic LIBS spectra of the most commonly used pigments and other materials involved was obtained. The knowledge of these spectra allowed us to identify the main constituents of the different layers in polychromes and to obtain compositional depth profiles.
