Item IMPACT OF ALUMINIUM ON STRUCTURAL, OPTICAL AND MORPHOLOGICAL PROPERTIES OF COPPER OXIDE NANOPARTICLES(Royal Book publishers / PSGR Krishnammal College for Women, Coimbatore., 2018-01-03) Vidhya Priya P; Balavijayalakshmi JMetal-oxide-semiconductors have been widely used for the optoelectronic applications like smart windows, solar cells, light emitting diodes and flat panel displays. Among all the metal oxides, copper oxide nanomaterials have a great attention due to its unique properties. It is mostly used in recent research works because of its low cost, rich availability and used in latent applications like antibacterial activities. Aluminium nanoparticles are a good conductor and it enhances the conductivity. Hence an attempt is made to synthesize CuO and Al doped CuO nanoparticles by hydrothermal method. The prepared samples are characterized by XRD, FT-IR, SEM, UV-Vis and PL analysis.The crystallite structures of CuO and Al doped CuO nanoparticles are identified by XRD analysis. The Fourier transform Infrared spectroscopy is used to determine the functional groups present in the prepared nanoparticles. UV-Vis Spectral analysis is performed to determine the band gap energy of the synthesized nanoparticles. PL spectral studies are used to study the optical properties of the nanoparticles. The morphology of the samples is determined by using scanning electron microscopy analysis. The impact of aluminium on structural, optical and morphological properties is investigated. The antibacterial activities of prepared CuO and Al doped CuO nanoparticles are probed.Item STRUCTURAL AND MORPHOLOGICAL INVESTIGATION ON ALUMINIUM DOPED COPPER OXIDE NANOPARTICLES(BIT, Sathyamangalam, 2017-08-17) Vidhya Priya P; Balavijayalakshmi JThe oxides of transition metals are an important class of semiconductors which have a wide range of applications because of its unique properties. Among these, copper oxide nanoparticles are of special interest because of its narrow band gap. Also, Aluminium is the most preferred dopant element because of its small ionic radius and low material cost. Hence in this present work, a novel idea of doping aluminium in copper oxide nanoparticles are carried out using hydrothermal method. The optical and structural properties of aluminium doped copper oxide nanoparticles are studied using UV-Vis and X-ray diffraction analysis. The FT-IR spectral analysis confirms the presence of functional groups in the prepared samples. XRD analysis shows that the synthesized nanoparticles are well crystalline in nature. The morphology of the samples are studied using scanning electron microscope. These nanoparticles may be tested for solar cell applications.Item INVESTIGATION ON THE HYDROTHERMAL SYNTHESIS OF PURE AND ALUMINIUM DOPED COPPER OXIDE NANOPARTICLES(Sri Ramakrishna Mission Vidyalaya College of Arts and Science, Coimbatore, 2016-12-15) Balavijayalakshmi J; Vidhya Priya PThe oxides of transition metals are an important class of semiconductors and have a wide attention due to their unique properties.
