Abstract

Abstract: ZnS∶Mn/poly(vinyl alcohol)(PVA) composite nanofibers were successfully prepared by using electrospinning technique and gas-solid reaction. The composites were characterized by means of TEM, SEM, FTIR, XRD, UV, PL measurements. The results indicate that the Mn\|doped ZnS nanocrystals with diameter about 3 nm were well-dispersed in PVA nanofibers through the coordination between —OH and Zn²⁺∶Mn, which prevented the ZnS∶Mn nanoparticles from aggregating in the nanofibers. Furthermore, the PL measurement demonstrates that the luminescence properties of Mn-doped samples changed significantly compared with the un-doped sample, which was caused by the influence of Mn centers.

Key words: Electrospinning, ZnS∶Mn nanoparticles, Poly(vinyl alcohol), Nanofiber
