Synthesis and optical properties of partially S-doped ZnO symmetric three-sided feather-like nanostructures

摘要

Partially S-doped ZnO symmetric three-sided feather-like nanostructures have been synthesized via a thermal evaporation and transport method. The products were grown in a one-step catalyst-free process. The synthesized nanostructures of both samples have nearly the same morphology although these contain different concentrations of sulfur (1.55 and 10.48 at.%). Our study suggests that the stems were S-doped while the teeth were not. These synthesized nanostructures were single-crystalline wurtzite structures. Room temperature photoluminescence (PL) spectra of the synthesized products showed three PL peaks in the ultraviolet, blue and green emission regions. The peaks were shifted towards high energy by sulfur doping. These symmetric three-sided nanostructures may be used in three-dimensional nanolasers in optoelectronics and nanorotors in nanomechanical systems.
