Fabrication of highly selective sensor based
on Mn-doped ZnO nanostructures

1
mol% of Mn -, Fe- doped and single phase hexagonally
plate ZnO have been synthesized by a simple low
temperature hydrothermal method using D-ribose as a
template. The influenceof thedoped specious on structural,
optical and sensing property was studied by X-ray
diffraction (XRD), scanning electron microscopy (SEM),
UV–vis spectra, photoluminescence (PL) and gas sensor
characterization system. The results show that the doped
specious have significant effect on morphology, crystallite
size, photoluminescence and sensing properties. Mn-
doped ZnO sensor shows selective response to acetone
in presence of CO and ethanol while, Fe-doped ZnO
does not show considerable response to CO, ethanol and
acetone gases. Probably, the crystal defects are detected
by photoluminescence account for the different sensing
behaviors. A possible mechanism of how a doped ZnO-
based sensor response to the target gas is also proposed
by density functional theory (DFT) calculations.
