XEOL (X-ray excited optical luminescence), PL (photoluminescence), CL (cathodoluminescence), and FLIM (fluorescence life-time imaging) are different modalities that can provide information from luminescent (fluorescent, phosphorescent) compounds, using different excitation probes: X-ray, ultraviolet and visible photons, or electrons. The use of these different approaches has increased considerably in recent years in heritage studies, as they make it possible to study the electronic properties of compounds, in some cases at trace level, which can be highly diagnostic of the composition and speciation of molecular markers in art, archaeological and paleontological objects –  to document objects history and alteration.

This one-day seminar is organised on the occasion of Veronica de Carvalho Teixeira's invited professorship at ENS Paris-Saclay.

This event was partially funded by the France 2030 programme "ANR-11-IDEX-0003" via Integrative Institute of Materials from Paris-Saclay University - 2IM@UPSaclay. It is part of the activities of the Collaborating Center "Atoms for Heritage" of the International Atomic Energy Agency (IAEA) and the Université Paris-Saclay.
