Thin Film Electrodes for Electrochromic Devices
Macalík, Michal ; Kadlec, Jaromír (referee) ; Nováková,, Sabina (referee) ; Sedlaříková, Marie (advisor)
The work deals with the deposition of layers for electrochromic device with different methods. Transparent electrically conductive layer of SnO2 was deposited by pyrolytic decomposition of peroxostannate solution. Hydrogen peroxide in starting solution contributes to the oxidation process of growth layers and to increase the electrical conductivity. Active electrochromic layer of WO3 was electrolytic deposited from the peroxotungstic acid solution. Optimal deposition time and the optimal annealing temperature of deposited layers were found. Passive electrochromic layer of V2O5 was deposited using dip-coating method from peroxovanadate solution. A contribution of solution diluted with distilled water was investigated. Found results were used to construct complete electrochromic device with polymer gel electrolyte.

Nanostructured sensors for detection of organic compounds
Šťávová, Karolína ; Fohlerová, Zdenka (referee) ; Hrdý, Radim (advisor)
This bachelor's thesis is focused on the fabrication of sensitive layers composed of an array of gold nanorods and their modifications. Firstly, a nanoporous mask is made from a layer of aluminum using a method called anodic oxidation. Afterwards electrochemical deposition of gold and polypyrrole or gold and mercury is carried out into the mask. The sensitive layer is characterized by the scanning electron microscopy and other methods for elemental analysis. A sensor with this type of sensitive layer can be used for the detection of various organic compounds.
