| description | Chemical vapor deposition (cvd) technique is the most common vapor
route technique uses by researchers to synthesize zno nanostructures. However, the
current in-situ doping approaches using cvd do not give many flexibilities for the
researchers to produce doped zno nanostructures. As the dopant solution is kept
outside the furnace, the aerosol assisted - chemical vapor depostion (aa-cvd) is
a potential in-situ doping technique because it offers many advantages such as
flexibility of controlling the doping concentration, doping duration, type of dopant
precursor and possibility of mass production of doped nanostructures. This project
started by setting up a cvd system to synthesize undoped zno rods without using
foreign catalyst. The study indicated that the optimum synthesis condition for
synthesizing undoped zno rods was using 0.3 g zn powder, 30 min synthesis
duration, and 5 cm distance of si substrates from zn powder at 650 °c. The average
length, diameter, aspect ratio and areal density of undoped zno rods are 2.99 ±0.13
pm, 0.54 ± 0.05 pm, and 5.6 ± 0.3, 2.9 ± 0.9 rods/pm , respectively. Subsequently,
ex-situ fe-doping was performed via spray pyrolysis on the pre-grown zno rods.
The physical properties of fe-doped zno rods prepared by ex-situ doping would be
used to compare with the fe-doped zno rods prepared by in-situ doping in the
subsequent phase. |
