Abstract :

Binary nano metal oxides are extensively pursued for their prominence in various fields of technological application for the development of nano structured materials to enrich their retail properties. Admits these transitional metal oxides, Copper oxide is determined to be a potential candidate due to its versatile structural, optical and thermal properties. The rare earth element, lanthanum was used as a dopant because of their tendency to boost the optical and thermal properties and tune the material in a desired way. Here the lanthanum doped and undoped CuO nanoparticles were synthesized using a swift and elegant co-precipitation synthesis. The crystallite size and the structural parameters was determined using the X-Ray diffraction spectra, the fingerprint vibrational modes were confirmed using the FT-IR spectra for a range of 4000 – 500 cm-1, the optical band gap for the material was understood from the UV-vis spectra for a range of 300 – 700 nm and the microstructural nature of the material was studied from the raman spectra from a range of 200 – 1350 cm-1. The morphological characteristics of the given material was seen using the TEM micrograph. The overall result of the effect of lanthanum on copper oxide were studied.
