ZnSe films with thickness of 50, 70 and 100 nm were prepared on Corning 7059 glass substrates at room temperature by applying continuous or periodically interrupted physical vapour deposition at very low deposition rates (0.2 and 0.5 nm s−1). Part

Homogeneous films from SiOx (x = 1.2, 1.3) were deposited on crystalline Si substrates by thermal evaporation of silicon monoxide in vacuum. A part of the films was further annealed at 1000 °C to grow Si nanocrystals in a silicon dioxide matrix. Hom
Nanocrystalline layers of ZnSe with thickness in the range 30-150 nm are deposited on Corning 7059 glass substrates at room temperature by thermal evaporation of ZnSe in vacuum. Periodically interrupted vapor deposition is used at various deposition

In the present work the synthesis of silver nanoparticles by the polyol method is investigated. The self-seeding polyol process was chosen from the number of variations of this method. In this approach AgNO3 was used as a precursor, poly (N-vinylpyrr

The possibility for tuned excitation of surface plasmon resonance in Ag-In and Ag-Sb films with different compositions and thicknesses was studied in terms of preparation and microstructural and optical properties. The analyses show that plasmon exci
