Abstract

Ba0.4La0.6−yEuyTiO3 (y = 0.01–0.04) nanorods were synthesized using simple hydrothermal technique. The mixed structure consisting of tetragonal and rhombohedral phases of the prepared nanorods was confirmed by X-ray diffraction patterns. The structural parameters were calculated and confirmed the tetragonal unit cells in the case of y = 0.01–0.04 samples. The surface morphology evidenced the nanorods like structures among all the samples using the FESEM and TEM studies. The y = 0.03 & 0.04 samples revealed the high dielectric constant values of 13,696 and 16,305 at 10 kHz indicating the applications in high storage capacitors. In addition, dielectric modulus and impedance spectroscopy analysis was done for having clear picture about the space charge polarization effect, relaxation dynamics and electrical conduction mechanism.
