Synthesis of Cu₂O Nanospheres and Cubes: Their Structural, Optical and Magnetic Properties

Abstract:

In this work, synthesis strategy of Cu₂O nanosphere and cube was elucidated and the structural, optical and magnetic properties were studied. Cu₂O nanospheres and cubes were synthesized by wet chemical method through selecting the appropriate amount of isopropyl alcohol (IPA) with distilled water as solvent. 5% of IPA yielded cubic shape Cu₂O and 30% of IPA yielded spherical Cu₂O. The phase purity was confirmed with powder XRD. The FTIR result exhibit Cu (I)-O vibrational band around 628 cm^-1 supports the XRD results. In Raman spectra weak band at 508 cm^-1 corresponds to Raman allowed mode. The IR active bands at 110 and 150 cm^-1 are observed because of the violation of selection rules which demonstrates the defects present in synthesized Cu₂O. Raman peaks at 218 and 415 cm^-1are assigned to multiphonon Raman scattering. The UV-Vis diffuse reflectance spectrum was recorded to calculate the band gap value. The band gap value calculated using Kubelka-Munk equation was 2.015 eV and 2.025 eV, respectively, for Cu₂O cube and nanosphere.
