These results suggest that the incorporation of Sn or other metal cations having significant covalent bonding or a strong preference for octahedral coordination in pyrochlore-based materials may have a detrimental effect on ionic conductivity.doi:10.1039/C3RA22704AMassey de los Reyes...
The crystal field strength, i.e., Dq/B increases due to the introduction of Al3+ ions with small ion radius (0.53 Å, CN = 6), which generates a close band of central atoms and ligand atoms. The emission band become wider and blue shift as the concentration of Al3+ ions increases...
Mixed ionic-electronic conductivityStannate pyrochloresOxide ion conductorsStudies on the Gd2Sn2-x-yMxAyO7 system (M=Ti and A=Ru; x=0.5, 1.0 and 1.5; y=0.2) were carried out and the conductivity of the compounds was analyzed in air. All the substituted compounds form ordered pyrochlore ...
