Investigation On Structural And Optical Properties Of La2comno6 Double Perovskite

Abstract

Lanthanum –based perovskite type oxides have received remarkable attention in recent years, due to its good optical, magnetic and electrical properties. Among them, La2CoMnO6 were considered to be a promising candidate for various applications like energy storage devices, gas sensors, catalysis etc. owing to its exceptional physical and multiferroic properties. Therefore, in this work, I had prepared La2CoMnO6 double perovskites using modified auto combustion method and its structural, and optical properties were investigated. The XRD analysis confirms the monoclinic structure with a space group of P21/n and its crystalline size were determined using Debye Scherrer‟s formula The optical properties of the prepared double perovskites were analyzed using the UV-Visible DRS spectra and its bandgap is observed to about 1.5 eV. Hence, the prepared double perovskite can be used as a fascinating candidate for various optoelectronic applications.
