Název v původním jazyce

The influence of annealing on the M/TiO2 thin films deposited by magnetron sputtering.

Popis výsledku v původním jazyce

The aim of this study is influence of the annealing on properties of metal-doped titanium dioxide (M/TiO2) thin films deposited by dc reactive magnetron sputtering and doped by silver, copper and gold. The as-deposited M/TiO2 films are amorphous. As is well known from literature, the highest photocatalytic efficiency was observed on the crystalline films with anatase structure[1]. This anatase structure is formed using high temperature of the substrate during deposition or post-annealing. To support crystallization we have annealed M/TiO2 films at 300°C during 1 hour. Crystalline structure of the films was observed by low angle XRD analysis. Optical properties were studied by UV/VIS spectrophotometry. The photocatalytic activity was evaluated from decomposition speed of aqueous solution of the Orange 7, exposed to UV light. A summarization of relations between as-deposited and annealed films properties, deposition parameters and photocatalytic activity was made.
