Well Defined Structures of SnOx Nanoparticles

Popis výsledku v původním jazyce

Highly organized nanostructured tin and tin oxide layers were prepared on silicon, silica and glass substrates by combination of nanosphere lithography, tin evaporation and plasma treatment. Template mask was made of self-assembled carboxylated polystyrene (PS) nanoparticles (NPs) of variable diameters by dipcoating method. The process of mask assembling was optimized so organized mono and bilayer of PS nanoparticles was achieved in about 30mm2. Vacuum evaporation of tin and subsequent mask displacementresulted in highly organized, trigonally or hexagonally arranged arrays of tin NPs. Distance, shape and size of particles is affected by type of the mask. Almost spherical NPs were prepared by treatment of nanostructured surfaces in RF argon plasma. Tinoxide nanostructured layers were obtained by oxidation of tin NPs after exposure to air or in Ar/O2 plasma. All prepared nanoarrays were characterized for their topographic (AFM) and chemical (XPS) properties.
