Nano fluorescent fibers prepared by electrospinning

In this study, electrospinning technique was used to prepare nano-ceramic fibers. In the preparation of the precursor solution, an appropriate amount of PVP was added to made up an appropriate PVP concentrationfor preparation of nano-fibers. After heat treatment, the following instruments include AFM, FE-SEM, HRTEM, and XRD were used to analyze for the same specimen. Part I: Prepared by using different heat treatment temperature to ceramic nano fluorescent fibers fo. It was found that higher temperature resulted in a larger the ceramic nanofiber crystalline with more closely spaced. Part II: we focus on the control the electrospinning fiber by changing collect and the ratio of the solution modulation to control morphology of the fibers. We found that a smooth and hollow or rough and solid fiber production to change the way the collector, which can be more regular and orderly arrangement. FE-SEM and TEM were used to explore its morphology and fiber diameter, identified whether and to achieve nanoscale continuous fiber. AFM scanning single nano-ceramic fibers was used to explore the nature of the surface morphology. Crystalline properties were characterized by XRD. Finally, we explored and examined optical properties by use PL spectrometer. This way can create electrospinning nano-fiber molecular structure and absorption, crystalline nature of the association and to establish correlation analysis techniques to explore the changing nature of its physical, optical, and crystal structure. In addition, it was successfully established a set of core technology, and can be deployed to formation fibers with smooth and hollow or rough and solid, and to produce a large area fibers after high temperature treatment.
