Effect of Codoping on the Electrical Properties of Magnesium- and Copper-Containing Bismuth Niobate with Pyrochlore-Type Structure
Bismuth niobate Bi 1.5 Cu 0.375 Mg 0.375 Nb 1.45 Ru 0.05 O 7‒δ with the pyrochlore structure co-doped with ruthenium was obtained by Pechini method. The distribution of Ru 4+ over Nb 5+ sites was established by structural analysis. According to the data of optical reflectance spectra, the optical ba...

with the pyrochlore structure co-doped with ruthenium was obtained by Pechini method. The distribution of Ru
4+
over Nb

sites was established by structural analysis. According to the data of optical reflectance spectra, the optical band gap decreases from 2.40 to 2.27 eV for the sample doped with ruthenium. A small amount of ruthenium in the system was found to result in an increase in conductivity by 0.5 orders of magnitude compared to Cu-Mg–substituted bismuth niobate, due to an increase in the electronic component of the conductivity. |
