Photoelectrochemical properties of titanium dioxide doped by metals
Vičarová, Monika ; Drbohlavová, Jana (referee) ; Dzik, Petr (advisor)
This thesis deals with the optimization of materials and processes for making layers of titanium dioxide enriched with metal nanostructured aggregates. These layers have a plasmonic effect in visible light radiation. Gold-doped titanium dioxide thin films were applied to the FTO glass substrate by spin-coating method and calcined at 450 ° C for 30 minutes. Two forms of titanium dioxide and two different gold precursors were used to make the layers. The structure of the layers was observed by optical and SEM microscopy. The photoelectrochemical properties of the prepared layers were studied by electroanalytical methods linear sweep voltammetry and chronoamperometry.

Printed UV senor based on photoelectrochemical cell
Vičarová, Monika ; Drbohlavová, Jana (referee) ; Dzik, Petr (advisor)
This thesis deals with the construction of a photoelectrochemical cell, which is used for detection of ultraviolet radiation by means of generated photocurrent in dependence on the intensity of incident radiation. The cell construction is based on a carbon electrode system with a titanium dioxide sensory layer and a UV curable electrolyte. Printing techniques such as screen printing, inkjet printing and pad printing were used to deposit individual layers. Carbon electrodes with sensory layer were studied through profilometric analysis, optical microscopy, and four-point probes. The viscosity of the liquid formulation of uncured electrolyte was characterized by rheometric measurement. Photoelectrochemical properties of the prepared cell for use as a UV sensor were investigated by cyclic voltammetry and chronoamperometry.
