Abstract

One of the effective ways to change the characteristics of a material is to dope it with a selected chemical element. Doping with metals and/or non-metals of titanium dioxide bronze phase, TiO2(B), improves some of its important electrochemical and electrophysical characteristics. Establishing the mechanisms responsible for them, requires knowledge of the electronic structure, positions in the crystal lattice, and distribution of impurity ions in the sample, as well as data on the forms of charge compensation in the sample under aliovalent substitutions. This paper presents the results of electron paramagnetic resonance (EPR) studies of nanodispersed TiO2(B) samples co-doped with various amounts of manganese, fluorine and nitrogen, aimed at obtaining information on all these issues.
