Compositionally controlled band gap and photoluminescence of ZnSSe nanofibers by electrospinning
2015
A simple, non-toxic, low-priced, and reproducible manipulation, which meets the standards of green chemistry, is introduced for the synthesis of ZnSxSe1−x nanofibers. ZnSxSe1−x nanofibers have been prepared in the entire composition range from ZnSe to ZnS by using a low-cost wet-chemical method. The effects of polymer (PVB) concentrations, reactant (S/Se) concentrations and reaction conditions (applied voltage, viscosity, and work distance) have been investigated. We have demonstrated that wurtzite ZnSxSe1−x showing a fiber-like morphology can be kinetically stabilized in the presence of an electrospinning system.
