Synthesis and optical property of one-dimensional spinel ZnMn(2)O(4 )nanorods
Spinel zinc manganese oxide (ZnMn(2)O(4)) nanorods were successfully prepared using the previously synthesized α-MnO(2 )nanorods by a hydrothermal method as template. The nanorods were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, UV-Vis absorpti...

| Sumario: | Spinel zinc manganese oxide (ZnMn(2)O(4)) nanorods were successfully prepared using the previously synthesized α-MnO(2 )nanorods by a hydrothermal method as template. The nanorods were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, UV-Vis absorption, X-ray photoelectron spectroscopy, surface photovoltage spectroscopy, and Fourier transform infrared spectroscopy. The ZnMn(2)O(4 )nanorods in well-formed crystallinity and phase purity appeared with the width in 50-100 nm and the length in 1.5-2 μm. They exhibited strong absorption below 500 nm with the threshold edges around 700 nm. A significant photovoltage response in the region below 400 nm could be observed for the nanorods calcined at 650 and 800°C. |
