采用静电纺丝技术与热处理方法相结合，通过在 H2S 气氛中于 500°C 下对电纺 ZnO 纳米纤维（作为模板）进行硫化来制备 ZnS 纳米纤维。具有闪锌矿结构的ZnS纳米纤维粗糙且不均匀，这被认为与加工条件有关。观察到带隙特征峰主要集中在 390 和 445 nm，分别对应于紫色和蓝色发射。这里演示的方法可能是制造其他一维纳米结构硫化物的通用方法，用于纳米级器件的潜在应用。
Using an electrospinning technique coupled with a thermal treatment approach, ZnS nanofibers have been prepared by sulfurizing the electrospun ZnO nanofibers (as a template) at 500°C in an H2S atmosphere. The ZnS nanofibers, with a zinc-blende structure, were found to be rough and uneven, which was considered to be correlated with the processing conditions. Band gap characteristic peaks mainly centered at 390 and 445 nm have been observed, corresponding to the purple and blue emission, respectively. The method demonstrated here could be a general approach of fabricating other one-dimensional-nanostructured sulfides for potential applications in nanoscale devices.
