Synthesis and characterization studies of MgO:CuO nanocrystals by wet-chemical method
چکیده انگلیسی


• Nanocomposites structures of MgO:CuO is prepared by wet-chemical method.
• Optical luminescence and Raman scattering of MgO:CuO is studied.
• Crystalline and molecular behaviors of nanocomposite crystals.
• Morphological results ensured the nanoporous structures of MgO:CuO.
• Opto/electrochemical properties of MgO:CuO are potential for device development.

In this report, we examine the progress in adapting these nanomaterials for several predominantly photonics device fabrication by wet-chemical method. Nanocomposite of magnesium oxide (MgO) with copper oxide (CuO) doped nanoparticles were characterized by X-ray powder diffraction (XRD) and the observed peaks are quite agreeable with the pure phase cubic structure. High-resolution transmission electron microscopic (HR-TEM) results reveal that the resultant nanopowders are porous and agglomerated with polycrystalline nano-entities. Field emission of selected-area electron diffraction (SAED) studies showed that the average size of the nanoparticles were 20 nm. Photoluminescence spectra of MgO:CuO were investigated, showing emission peaks around 375 nm relating to new energy levels induced by defects or defect levels generation and confocal micro-Raman images indicated that the chemical molecular vibrational band structure and morphology of the product which is spherical shaped nanoparticles with an average particle size of ∼25 nm with standard deviation. The electrochemical response of MgO:CuO which is proves that the nano-copper/magnesium has high functionality due to the small size and it has higher electrochemical activity without any modifications.
