摘　　要：半导体纳米粒子因其独一无二的光学及电学性质而引起了人们广泛的研究兴趣．硫化锌纳米粒子作为重要的Ⅱ-Ⅵ半导体材料，在催化剂、电学、光学器件上都具有潜在的应用前景．尤其是硫化锌掺锰的纳米粒子在荧光发射等方面与无掺杂的硫化锌纳米粒子相比，表现出不同的性质．这使其有可能作为一种新型的材料被应用到光学器件上．最近，人们将无机纳米粒子与有机高分子复合利用LBL膜、自组装等方法制备出了无机有机复合材料．目前，静电纺丝法作为制备超细纳米纤维的简单有效的方法已被用到多种材料的制备上．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 Zn^2＋ ： 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.
