报道了直径在纳米到微米范围内的氧化锌纤维的形态和光学性质。采用聚乙烯醇（PVA）和醋酸锌通过静电纺丝成功制备了PVA/醋酸锌有机/无机杂化纳米纤维。将杂化纤维在空气中高温煅烧得到纯氧化锌纤维。通过扫描电子显微镜 (SEM)、原子力显微镜 (AFM)、X 射线衍射 (XRD) 和拉曼光谱对纳米纤维进行了表征。 325 nm 激发下的光致发光光谱显示出 3.13 eV 处的紫外发射和 2.21 eV 处的绿光发射。这些纳米纤维可用作纳米级光电应用中的发光器件。
The morphology and optical properties of zinc oxide fibres with diameters in the nanometre to micrometre range are reported. The PVA/zinc acetate organic/inorganic hybrid nanofibres were successfully prepared by electrospinning using polyvinyl alcohol (PVA) and zinc acetate. Pure zinc oxide fibres were obtained by high-temperature calcination of the hybrid fibres in air. The nanofibres were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), x-ray diffractometry (XRD) and Raman spectroscopy. The photoluminescence spectra under excitation at 325 nm showed an ultraviolet emission at 3.13 eV and a green emission at 2.21 eV. These nanofibres could be used as light emitting devices in nanoscale optoelectronic applications.
