Abstract: Abstract: We report high dielectric tunabilities of (1−x)Ba(Zr0.2Ti0.8)O3 −x(Ba0.7Ca0.3)TiO3 (BZT–xBCT) (x=0.15, 0.30, 0.40, 0.45, 0.50, and 0.55) thin films prepared by a sol–gel method. The films show a pure perovskite structure with random orientation. They have moderate dielectric constant ranging from 350 to 500 and low dielectric loss near 3.0% at 1kHz with 0V bias at room temperature. The dielectric tunability of the BZT–0.55BCT thin films is up to 65% at 400kV/cm and 100kHz. The films exhibit a high optical transmission in the range of 420nm–1500nm. Their optical band gap energies are about 3.90eV. [Copyright &y& Elsevier]
