Spherical assemblies of CdS nanofibers in poly(vinyl acetate) by γ-irradiation

Abstract

γ-irradiation method was used for the first time to prepare spherical assemblies of 10 × 50nm CdS nanofibers in poly(vinyl acetate) with diameter of 120nm. The irradiation reaction between cadmium chloride and carbon disulfide, and the polymerization of monomer vinyl acetate occur in the one-spot heterogeneous system, leading to the formation of spherical assemblies of semiconductor in polymer and the resulting CdS nanofibers with a good crystallinity. The preparation was done at room temperature and ambient pressure.
