title: Synthesis of aligned zinc sulfide nanostructures and the influence of experimental conditions on their morphologies and phase.
abstract: A novel aligned flower-like array and single-crystal nanosheets composed of ZnS quantum wires were fabricated via a simple solution route. In the method, ZnCl2 chemicals reacted with Na2S in 50 ml of ethylenediamine (en) solution containing different amounts of hydrochloric acid (HCl) at 70-80 degrees C. After annealing at 500 degrees C for 1.5 h, wurtzite phase ZnS nanoscaled materials were synthesized. When the amount of HCl was 2 ml and 3 ml, respectively, flower-like structure and nanosheets were obtained. The products were characterized by X-ray diffraction, transmission electron microscopy, high-resolution electron microscopy (HREM), and electron diffraction (ED). The influences of concentration, temperature, and reaction time on the morphologies and phase of ZnS nanostructures were also studied. The photoluminescence peaks are located at approximately 308 nm and approximately 410 nm. The formation mechanism is also discussed here.
