Abstract
We report the hydrothermal-growth of 3D flower-like Cu0.45Mn0.55O2 nanowhiskers self-assembled by interconnecting single-crystalline nanosheets. FESEM analysis shows that the size of Cu0.45Mn0.55O2 nanowhiskers is in the range of 1-2 μm. Structural investigations reveal that the phase of Cu0.45Mn0.55O2 nanostructures is insensitive after exposure to electron beam irradiation. The novel photoluminescence spectra of the as-prepared nanograined Cu0.45Mn0.55O2 exhibit prominent emission bands located in green-violet spectral region. Ultraviolet-visible absorption spectrophotometry was used to determine the absorption behavior of Cu0.45Mn0.55O2 nanostructures and a direct optical band gap of 2.53 eV was acquired by the Davis-Mott model.
