Nanoscale Investigation of the Degradation Mechanism of a Historical Chrome Yellow Paint by Quantitative Electron Energy Loss spectroscopy Mapping of Chromium Species

摘要

Since the 19th century, the industrial expansion stimulated the development of synthetic pathways to many new materials, including various pigments of the chrome yellow family (PbCrO4, PbCr_(1-x)S_xO4 (0.1≤x≤0.8), (1-x)PbCrO4·xPbO), cadmium yellow (CdS), emerald green (Cu(C2H3O2)2·3 Cu-(AsO2)2), and viridian green (Cr2O3·2H2O).
