dc.description.abstractNanorods of titanium oxide (TiO_2) were obtained by thermally activated growth process carried out on pellets of nanocrystalline powder with mixed anatase and rutile structures. The nanostuctured array consists of nanorods with length between 300 min and 1 mu m and hexagonal cross section of 100-200 nm diameter. Herein it is shown that one can obtain information on the nanostructure growth from cathodoluminescence emission spectra. Vie growth process of the rods is mainly associated with the presence of the anatase phase. The keyrole of characteristic defects in semiconductor oxides, namely oxygen vacancies and Ti_(n+) ions is discussed.
