Abstract
In this work, we investigated the effect of aluminum content on optical, electrical and dielectric properties of mixed metal oxides (MMOs), obtained from calcination at 726 K of solid solution series based on nitrate intercalated Mg1-xAlx Layered Double Hydroxides (x = 0.167, 0.20, 0.25, 0.33). Subsequently, the MMOs were characterized by X-Ray Diffraction, and analyzed by Inductively Coupled Plasma, Scanning Electron Microscopy, Diffuse Reflectance Spectroscopy and Impedance Spectroscopy. It was found a shift of light absorption towards shorter wavelengths, and an increase of conductivity and dielectric constant when the aluminum content increased. Higher aluminum content exhibited strong ultraviolet light absorption with average band gap of 6.29 eV, and also manifested high reflectance in visible and near-infrared wavelengths, whereas lower aluminum content showed lower values of conductivity, dielectric constant and dielectric loss tangent. Moreover, the electrical, dielectric and optical parameters of MMOs were reported and discussed.
