The semiconductor zinc sulfide (ZnS), which belongs to the II-VI family, has a direct
wide bandgap about 3.68 eV and 3.911 eV for zinc blende structure and wurzite structure,
respectively. One-dimensional ZnS nanofibers have been prepared by using zinc nitrate,
thiourea and poly(vinyl butyral) as precursors dissolved in ethanol via a electrospinning
process. By changing the electrostatic voltage, velocity of the liquid, distance between needle
and receiver board, the main effects of different process parameters on the diameter of the
ZnS/PVB precursors electrospun fiber have been discussed. The structure, morphology and
composition of the samples were characterized by using X-ray diffraction, scanning electron
microscopy, and energy dispersive X-ray spectroscope.
