文摘
By carefully controlling the reacting time, temperature, and humidity, we have prepared Co3O4 nanowires byheating a pure cobalt foil in atmosphere. Scanning electronic microscopy demonstrates that the nanowireshave a diameter ranging from 20 to 100 nm and their typical lengths are in the range of 10-20 m. X-raydiffraction, X-ray photoelectron spectroscopy, Raman spectrum, and transmission electronic microscopyanalyses demonstrate that the nanowires are Co3O4. The optical property of the nanowires is determined byphotoluminescence spectrum. The magnetic behavior of it is investigated by a magnetic property measurementsystem. The nanowires exhibit some novel optical and magnetic properties, which are different from its bulkmaterial.
