Preparation and photoelectric properties of indium tin oxide depositional optical fiber by centrifugal spinning

The purpose of this paper is to prepare an integrating light propagative, transparent and conductive optical fiber. This optical fiber is made by the coating of a thin layer of indium tin oxide (ITO) nanofibers. ITO nanofibers are fabricated via centrifugal spinning process and wrap around the quartz optical fiber. Field emission scanning electron microscopy, X-ray diffraction analysis, UV–Vis spectrophotometer, Avometer and Luminance colorimeter are used to characterize the morphology, crystal structure and photoelectric properties of ITO-coated optical fiber. Results show that the resistivity of ITO-coated optical fiber is around 0.87 (Ω cm); the average optical transmittance is more than 85 % in the visible range, and the ITO-coated optical fiber has a certain light propagation. This work laid the groundwork for future application in fiber sensors.
