摘要

In this work, Vis-NIR steady-state photoluminescence (PL) emission and Vis-NIR reflection spectroscopy were used in order to investigate the effects induced on modern paint layers by LQS Nd:YAG(1064 nm) laser at subablative fluences. Cadmium yellow (Cdy), lithopone white (Liw) and chromium oxide green (Crg) pigments with and without oil matrix were investigated. The setup proposed allowed collecting reliable information on PL, color and morphology changes upon laser irradiation. Furthermore, the results achieved led to recognize, for the first time, the oil matrix alteration as the early trigger of the photothermal effects.
