초록
In this work, a series of BaTiO3-based ceramic materials, Ba(Al0.5Nb0.5)xTi1-xO3 (x = 0, 0.04, 0.06, 0.08), was synthesized usinga standard solid-state reaction technique. In the temperature range of 100~380 K, the frequency-dependent dielectric andelectrical modulus properties were studied. A colossal dielectric permittivity (>1.5×104) and low dielectric loss (< 0.01) weredemonstrated at the optimal doping concentration x = 0.04. The observed dielectric behavior of Ba(Al0.5Nb0.5)xTi1-xO3 ceramicscan be attributed to the Universal Dielectric Response. The complex electrical modulus spectra indicate a significant decreasein capacitance and permittivity of the grains with increasing co-doping concentration. Our results provide insight into the roleof donor and acceptor co-doping on the properties of BaTiO3-based ceramics, which is important for their use in dielectric andenergy storage applications.
