Abstract
The multi-functional material Li2LaFeTiO6 belonging to double perovskite family is expected to be non-cubic structure and interaction between La and Fe introduce octahedral B-site cation dis-order or anti-site effect. The material is prepared by conventional solid state reaction technique and its formation has been checked through X-ray diffraction (XRD). It is observed that material is orthorhombic crystal structure with Pbnm space group. Scanning electron microscope (SEM) picture of the surface uncovers distinctive shape and sizes of the grains are consistently appropriated all through the surface leaving not many voids. Energy dispersive spectroscopy (EDX) study indicates there is no impurities are seen in the present material. Fourier transform infrared (FTIR) spectroscopy revels the perovskite phase and different modes of vibration. The room temperature UV–Visible spectroscopic analysis reveals material is a potential candidate photovoltaic/solar cell device. The dielectric and electrical measurement is carried out using computer control LCR analyzer. The room temperature dielectric constant and loss tangent of the material is respectively > 400 and < 0.1 which reflects it can be used for multi-layer capacitor and micro-electronics.
