Influence of immerse time on the properties of zinc oxide nanostructures

Abstract

Zinc oxide (ZnO) is an emerging optoelectronic material in large area electronic applications due to its various functional behaviors. We present the fabrication and characterizations of ZnO nanostructures. The ZnO nanostructures consisting of nanorods were synthesized using sol-gel hydrothermal technique on oxidized silicon (Si) substrates. In the fabrication of ZnO nanorods, the oxidized Si substrates were immersed in ZnO aqueous solution for different times ranging from 3.5 hours to 5 hours. The surface morphologies of the ZnO nanorods were examined using scanning electron microscope (SEM). In order to investigate the structural properties, the ZnO nanorods were measured using Xray diffractometer (XRD). The optical properties were measured using photoluminescence (PL) spectrophotometer. The influence of the immerse time on the properties of the realized ZnO nanostructures will be revealed and discussed in this paper.

Properties of ZnO thin films deposited on (glass, ITO and ZnO:Al) substrates

“…The cracks in the films deposited on glass may be attributed to an uncompleted reaction. Many authors have investigated the surface morphology of ZnO thin films obtained by different methods and deposited onto various substrates in the literature [29][30][31][32][33].…”

Hydrothermal Growth of Zinc Oxide (ZnO) Nanorods (NRs), Structural, and Chemical Composition Studies for pH Measurement Sensor Applications

“…One of the most versatile and studied metal oxide material is the zinc oxide (ZnO), which exhibits the excellent physical, chemical, electrical, optoelectronic properties and piezoelectric dual properties. Thus, they are highly suitable for a diverse application (11)(12)(13)(14). One-dimensional (1D) Zinc oxide (ZnO) which have a direct wide band gap (3.37eV) semiconductor with a large excitation binding energy (60 meV) at room temperature.…”

Investigation of Influence of Spin Coating Parameters on the Morphology of ZnO Thin Films by Taguchi Method

“…results in bigger grains and the surface roughness area increases with the increasing precursor concentration. Ilican et al [13] studied the effect of chuck speed between 3000 and 5000 rpm for the preparation of thin films, which was concluded that greater the chuck speed lower was the grain size of the crystallite. The texture coefficient decreased with increase in chuck rotation.…”
