Abstract

At room temperature and ambient atmospheric pressure, one dimension α-Bi₂O₃ nanowires were synthesized successfully by solution precipitation method, an efficient and convenient route, in the acetone-water mixed solvent system with the assistance of oleic acid (capping agent) and n-heptane (oil phase). X-ray diffraction (XRD) and field-emission scanning electron microscope (FE-SEM) were employed to characterize the obtained products, which were 50-100 nm in diameter, 10 μm in length, and with aspect ratio of 100Symbolm@@200. Mechanism analysis shows that oleic acid as capping agent plays an important role in the growth control of nanowires. According to the UV-visible diffuse reflectance spectrum, the as-prepared α-Bi₂O₃ nanowires present photo-absorption property from UV light region to visible light range (shorter than 455 nm). The fluorescence spectrum shows broad emission (400-600 nm).
