Study of Photodestruction of Pigments of Various Chemical Composition Under Laser Exposure

Abstract

This article presents an overview of current research on the photodegradation of pigments of various chemical compositions under laser irradiation. The main groups of pigments-organic, inorganic, and those containing photocatalytically active components and their sensitivity to light and laser are examined. The mechanisms of degradation, including thermal and photochemical effects, as well as combined effects, are discussed. Modern methods for studying photodegradation are presented: X-ray diffraction, microscopy, spectroscopy, colorimetry, and controlled laser irradiation.
