Application of Aluminum Foil as a Sers-Active Substrate in the Study of Artistic Pigments
摘要
The use of aluminum foil as a low-cost and promising SERS-active substrate is proposed. Aluminum foil demonstrated plasmonic properties comparable to and in some cases even superior to those of traditional SERS-active substrates based on gold nanoparticles in model experiments with various artistic pigments. The inorganic pigments used in samples taken from Southern Landscape supposedly by A. Kuprin and The Virgin and Child from the Church of St. John the Baptist in Borovtsy were identified. The time limits of their creation were defined.
