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

Abstract

Partially S-doped ZnO symmetric three-sided feather-like nanostructures havebeen synthesized via a thermal evaporation and transport method. The productswere grown in a one-step catalyst-free process. The synthesized nanostructures ofboth samples have nearly the same morphology although these contain differentconcentrations of sulfur (1.55 and 10.48 at.%). Our study suggests that the stemswere S-doped while the teeth were not. These synthesized nanostructures weresingle-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 energyby sulfur doping. These symmetric three-sided nanostructures may be used inthree-dimensional nanolasers in optoelectronics and nanorotors in nanomechanical systems.
