Established that the gain of the Raman signal of molecules of rhodamine 6G molecules and Tilorone maximum substrates for SERS-made based on lateral ordered gold nanoislands and nanostructures such as "core-shell" SiO2-Au, which amounts to (0.1-6)*10 6 * . It is shown that this value does not decrease by more than 20% in one month. Found that parameters such as repeatability characteristics, Raman amplification signal uniformity across the substrate surface in the best SERS-substrates laterally arranged nanoislands. However, these substrates is difficult to get the most plasmon absorption band in the 514 nm line is necessary for an argon laser. It was established that this spectral region effectively use nanostructures such as "core-shell" SiO2-Au. Product Description popup.authors Грещук О.М. Джаган Володимир Миколайович Жолобак Н.М.
