AbstractLuminescence enhanced by new structure of plasmonic platform with aluminum oxide (Al2O3) buffer layer deposited on gold nanostructures is investigated. Regularly distributed gold nanostructures of average dimension of 50 mu formed the active part of plasmonic platforms. They were manufactured on Corning 1737 glass substrate by melting of gold thin film. The nanostructures were coated by dielectric Al2O3 thin film with thickness of 6 nm deposited by atomic layer deposition (ALD) method. Thin film of Valrubicin as a luminescence material was deposited on prepared substrates by spin-coating technique. Luminescence spectra show that designed plasmonic platform with Al2O3 thin film between gold nanostructures and Valrubicin enhanced fluorescence intensity by about 4.5 times.
