Abstract
Al2O3 doped TiO2 samples were prepared by the simple sol-gel method. The prepared samples were annealed at 400°C for 1 h in an open air atmosphere. The dielectric properties, AC electrical conductivity (σac), dielectric constant (ε′), dielectric loss (ε″) and the loss tangent (tan δ) of the prepared Al2O3 doped TiO2 nanocomposites were studied under a wide frequency and temperature range. The dielectric loss values of the prepared samples were measured at 50 Hz and 5 MHz and the values were found to be in the range of 0.11–1.73 at 40°C and 0.13–4.39 at 100°C. The microstructures of the prepared samples were also studied using high-resolution transmission electron microscopy (HRTEM) analysis.
