Investigation of electrical and dielectric properties of complex perovskite Gd2/3Cu3Ti4O12 and Gd2/3Cu3Ti3.95Co0.025V0.025O12 ceramic synthesized via novel semi-wet route

Abstract

Gd2/3Cu3Ti4O12 (GCTO) and Co V-doped Gd2/3Cu3Ti4O12 (GCTCVO) ceramic nano-particles were synthesized by utilizing a cost-effective chemical route. XRD pattern analysis confirms single-phase formation of Gd2/3Cu3Ti4O12 (GCTO) and Co V-doped Gd2/3Cu3Ti4O12 (GCTCVO) ceramic. XPS analysis verified the correct oxidation states of various elements. Elemental composition was determined using EDS. The dielectric constant of GCTO ceramic reached its peak at 726, measured at 545 K and 1 kHz, while it reached its peak at 217, measured at 563 K and 1 kHz for GCTCVO. It was also observed that both ceramic show Maxwell relaxation behavior. The tangent loss value of the GCTO and GCTCVO ceramic was noted as 0.08 and 0.13 at 304 K and all measured frequency. © The Author(s), under exclusive licence to Springer Nature B.V. 2024.
