Ionic conduction properties of nanocrystalline Er₂Ti₂O₇ functional material
The rare-earth titanate Er₂Ti₂O₇ nanoceramic prepared by the modified combustion technique exhibits a cubic pyrochlore structure with the space group 3. Powder XRD and vibrational spectroscopic tools have been used for structural identification and confirmation. The detailed optical and photolumines...

| description | The rare-earth titanate Er₂Ti₂O₇ nanoceramic prepared by the modified combustion technique exhibits a cubic pyrochlore structure with the space group 3. Powder XRD and vibrational spectroscopic tools have been used for structural identification and confirmation. The detailed optical and photoluminescence (PL) properties of the sample have been analyzed using UV-Vis diffuse reflectance spectroscopy and PL spectroscopy. Impedance spectroscopic studies have revealed that the material exhibits conduction by hopping of ions, which increases with temperature. Z-View software has been used to fit the impedance data and deduce the electrical parameters of the samples from the equivalent circuit. The grain activation energy is less than that of the grain boundary, which implies that grain conduction is predominant in the sample. The optical and electrical studies confirm that the material is a possible candidate to fabricate optical devices and construct solid oxide fuel cells.
