加热对ZnS:Mn/聚乙烯吡咯烷酮纳米纤维的影响

摘要

ZnS:Mn/PVP fibers are fabricated by the electrospinning technique. Three kinds of solvent are used in the experiment: they are water, ethanol and N,N-dimethylformamide. Scanning electron microscopy, transmission electron microscopy, fluorescence spectrophotometer, X-ray diffractometer were employed in this article. By the method of heating, the effect on the morphology and properties of the composite nanofibers is studied. The separating state of fibers and the crystallinity of the particles in the fibers were increased. This kind of fibers has potential application in luminescent area.%通过静电纺丝的方法制备了具有发光特性的ZnS:Mn/聚乙烯吡咯烷酮纳米纤维,电纺溶液中的溶剂是DMF、水、乙醇,使用了扫描电子显微镜,荧光光谱仪,透射电子显微镜,X-射线衍射仪,研究了加热对电纺溶液中含有DMF溶剂的电纺纤维的影响,结果是纤维之间的分离程度提高,纤维内部的纳米粒子变得清晰,纤维内部粒子的结晶度提高,该纤维在发光领域有着潜在应用.
