“…This wavelength was closely matched the others reported value [17]. Another researcher have reported that the synthesis of CuONPs can be monitored by the formation of SPR at 415 nm [18]. Various reports have established that the SPR band of copper nanoparticles were observed between 620 to 710 nm [19].…”

Copper oxide nanoparticles (CuONPs) were green synthesized using aqueous extract of Cordia myxa L. leaves as reducing and capping agent. The synthesized nanoparticles were characterized by UV-visible spectrophotometer, FTIR, X-ray diffraction, scanning electron microscope and atomic force microscope. The prepared copper oxide nanoparticles showed surface plasmon resonance centered at 400 nm. The optimized condition for the synthesis of copper nanoparticles revealed that the aqueous extract of Cordia myxa L. leaves:copper sulfate ratio was 1:3, pH was 9 and copper sulfate concentration was 40 mM. FTIR results showed that stabilization and formation of CuONPs were due to phenolic groups and amines in plant extract. The XRD pattern showed that the particles are monoclinic in nature. The crystalline morphology and size of the nanoparticles were determined by scanning electron microscope. Presence of elemental copper was revealed by EDX analysis. Size range was from 20 to 106.81 nm was determined by atomic force microscope.

In this paper, brief reviews for the synthesis of copper oxide nanoparticles by the different green routes are described. Since last few years, synthesis of nanoparticles has been attracted considerable attention. The metal oxides are important technology materials used as antibacterial, antioxidant, antifungal as well as catalysts in chemical industries and in electronic and photonic devices. Due to the applications in advanced technologies, researchers have focused more on synthesis of CuO nanoparticles with improved, cost effective ecofriendly synthetic strategies. Copper oxide nanoparticles appear as a brownish-black powder. They can be reduced to metallic copper when exposed to hydrogen or carbon monoxide under high temperature. Copper oxide nanoparticles are used in wide range of applications such as biological, catalysis, gas sensors, magnetic storage media, batteries, solar energy transformer, semiconductors, and field emission. CuO, as a P-type semiconductors exhibiting narrow band gap, have attracted great attention due to its potential application in Nano devices such as electronic, optoelectronics. …………………………………………………………………………………………………….... Introduction:-During the last few decades, the interests of scientists are increasing continuously day by day in the field of science and technology at the nanometer range. Nano-science and nanotechnology is supposed to wrap all fields of science and technology because any material particle is made up of atoms and molecules [1]. In science and technology, was considered well-progressed interdisciplinary field of research in last few year. Particularly metal oxide nanoparticles have extensive well-known their application of in many fields of science including chemical industry, electronics, biomedical sciences, biosensor, molecular catalysts, magnetic materials and drug gene delivery due to their physical and chemical properties different from those in the bulk material [2]. Main focus of nanoscience and nanotechnology is synthesis of new nanoparticles with various sizes and new morphology. Due to change in morphology strongly effects on their broadly varying properties. Much attention attracted by nanoparticles on account of their unique properties and energetic application which are strongly influenced by their size, morphology and structure. Cupric oxide nanomaterials have attracted much attention on account of their distinctive properties among other metal oxides nanomaterials [3]. Cupric oxide nanoparticles have got great consideration because it is
