Synthesis and growth mechanism of Zn0.5Cd0.5S nanohexagon dendrite
Published online by Cambridge University Press: 25 November 2014
Abstract
Hierarchical Zn0.5Cd0.5S nanohexagon dendrites were synthesized by a one-step hydrothermal method. The Zn0.5Cd0.5S nanohexagon dendrites were made up of nanohexagons with a side length of about 90 nm. The nanohexagons were regularly arranged forming as embranchments which were parallel to each other along certain hexagonal directions. Furthermore, these embranchments made up primary trunks shaping as dendrites. The growth mechanism of Zn0.5Cd0.5S nanohexagon dendrites was proposed in which molecular soft template and lowest energy principle played key roles. By adjusting the composition of the reactants, a series of ZnxCd1–xS solid solutions could be obtained. The morphology of the synthesized ZnxCd1–xS depended much on the x value. The UV-vis spectra absorb edges of the ZnxCd1–xS samples continuously shifted indicating the changes of the band gap.
