ABSTRACT
ZnO nanoparticles is a versatile materials with a wide range of potential application.
Hydrophilic and hydrophobic properties of ZnO materials strongly influence its
self-cleaning capacity and applicability. This research aims to ascertain the various
concentration of Se doping affecting the ZnO:Se nanorod coating's optical,
structural, surface morphology, elemental composition, and wettability behavior.
The properties are studied by Ultraviolet-Visible (UV-Vis) Spectroscopy, X-ray
Diffraction (XRD), Field Emission Scanning Electron Microscope and Energy
Dispersive X-ray (FESEM-EDX) and water contact angle (WCA). ZnO:Se
nanorods are synthesized on a glass substrate using a combination of Successive
Ionic Layer Adsorption Reaction (SILAR) and Chemical Bath Deposition (CBD)
method. The UV-Vis spectrum shows that the strong absorption peak of the ZnO:Se
nanorods appears in the range of 200-380 nm for all samples. Doping of Se slightly
changs the bandgap energy of pure ZnO nanorods by approximately ± 0,006 eV.
The XRD test results confirm the growth of ZnO nanorods having a hexagonal
crystal structure with a preferential orientation of the (002) plane. The addition of
Se doping results the ZnO peak position to slightly shift towards a smaller angle.
The crystal size is found to be in the range of 27–40 nm. With increasing
concentration of Se doping in the ZnO:Se sample, the crystallite size is smaller.
Surface morphology studies show that the geometric shape of the ZnO:Se layer is
nanorods with a hexagonal cross section. The EDX test shows that Se elements are
successfully doped into ZnO nanocrystals. The wettability study shows that the Sedoped
ZnO layer has better hydrophilic properties than the pure ZnO layer.
Hydrophilic ZnO:Se nanorod coatings with a bandgap energy of ~3,339 - 3,345 eV
will potentially be applied as self-cleaning materials for solar panel protection,
photocatalyst, and as well the self-cleaning glass applications in architecture.
