Morphological, optical, and Raman characteristics of ZnO nanoflakes prepared via a sol–gel method
Two-dimensional (2D) ZnO nanoflakes were grown on thin aluminum layer, deposited on silicon substrate, using a sol–gel method. The surface morphologies of ZnO nanoflakes at different precursor concentrations were studied using scanning electron microscopy (SEM).
Effect of different seed solutions on the morphology and electrooptical properties of ZnO nanorods
The morphology and electrooptical properties of ZnO nanorods synthesized on monoethanolamine-based seed layer and KOH-based seed layer were compared. The seed solutions were prepared in monoethanolamine in 2-methoxyethanol and potassium hydroxide in methanol, respectively. Zinc acetate dihydrate was as a common precursor in both solutions. The nanorod-ZnOs were synthesized via the spin coating of two different seed solutions on silicon substrates followed by their hydrothermal growth.
Sol–gel synthesis of Pd doped ZnO nanorods for room temperature hydrogen sensing applications
A sol–gel spin coating technique was described for the synthesis of Pd doped ZnO nanorods for hydrogen sensing applications. The nanorods were hexagonal in shape, 50–100 nm in diameter and uniform in distribution. They exhibited homogeneous surfacemorphology, c-axis orientation and excellent crystalline properties. The synthesized nanorods were used to sense and detect hydrogen in a homemade gas chamber.
Impact of hydrogen concentrations on the impedance spectr behavior of Pd-sensitized ZnO nanorods
ZnO nanorods were synthesized using a low-cost sol-gel spin coating technique. The synthesized nanorods were consisted of hexagonal phase having c-axis orientation. SEM images reflected perpendicular ZnO nanorods forming bridging network in some areas. The impact of different hydrogen concentrations on the Pd-sensitized ZnO nanorods was investigated using an impedance spectroscopy (IS)
Study of frequency dependent electrical properties of ZnO nanorods
The purpose of the current research is to use impedance spectroscopy to study the AC parameters that varied with frequency such as impedance, dielectric constant and conductivity of ZnO nanorods MSM structure in the range of 1 Hz to 10 MHz under atmospheric conditions
Characterisation, analysis and optical properties of nanostructure ZnO using the sol-gel method
Nanostructure ZnO was grown on thin aluminium layer, deposited on silicon substrate using the sol–gel method. The surface morphologies of nanostructure ZnO at different precursor concentrations were studied using scanning electron microscopy
