摘要：

In this work photocatalytic properties of TiO2 thin films doped with 8.51 at. % of Nd were described. The self-cleaning phenomenon of thin films was discussed together with the structural, optical and surface properties of prepared thin films. Transparent coatings based on titanium dioxide were manufactured by high-energy reactive magnetron sputtering process. Incorporation of Nd during sputtering process results in amorphous behavior, without a significant influence on transparency and colour as compared to the undoped TiO2-rutile matrix. Nevertheless, doping with neodymium doubles the photocatalytic activity of the matrix due to higher quantity of photo-generated charge carriers and more efficient mechanism of energy transfer.
