Controllable synthesis of thioglycolic acid capped ZnS(Pn)_(0.5) nanotubes via simple aqueous solution route at low temperatures and conversion to wurtzite ZnS nanorods via thermal decompose of precursor

摘要

In the present paper, we report the successful synthesis of a thioglycolic acid capped ZnS(Pn)_(0.5) nanotubes (Pn = propanediamine) by a simple aqueous solution route employing ZnS(Pn)_2 and TGA as a reactant at relatively low temperature. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), ultraviolet-visible (UV-vis) spec-troscopy, photoluminescence spectroscopy (PL), Fourier transform infrared (FT-IR) spectroscopy, and thermogravimetric-differential thermal analysis (TG-DTA). The effect of TGA concentration, on shapes and size of as-prepared product has been investigated. The thioglycolic acid capped ZnS(Pn)_(0.5) nanotubes showed considerable blue shift in comparison of bulk ZnS because of quantum confinement effect.
