【摘要】 采用模板生长法在 Si 衬底上制备了具有线形结构的 ZnO．样品的晶体结构、形貌及光致发光性使用 XRD、AFM、SEM 及 PL 谱进行表征。结果表明所制备的线形 ZnO 为六方纤锌矿型晶体结构,线宽度大约为1μm,长度约10～30μm,具有良好的发光特性。我们对这种线形结构的形成作了推测。更多还原

【Abstract】 ZnO fibre was synthesized on Si substrate via a PVA-assisted chemical solution method.Crystal structure,morphology and UV photoluminescence property were characterized by XRD,AFM,SEM and PL spectra.XRD indicates that as-synthesized sample is wuttzite structure.Strong near band emission of the synthesized ZnO fiber was observed at room temperature with the measurement of photolummescence.A possible mechanism for the formation of ZnO fiber was also proposed.更多还原
