Influence of Substrate’s Alignment Strategy to the Growth of ZnO Nano-Petals via Solution-Immersion Method

Abstract:

Zinc oxide (ZnO) nanostructures were successfully grown on gold-seeded Si substrate prepared by a solution-immersion method using a novel mixture of an aqueous solution of Zinc nitrate hexahydrate (Zn (NO₃)₂.6H₂O) with a non-toxic, odourless urea (CH₄N₂O) as a stabilizer. Structural and optical properties of resultant ZnO thin films were investigated by X-Ray Diffraction, FESEM and Photoluminescence Spectroscopy (PL). Clusters of ZnO micro-flower with serrated broad petals with the thickness of petals approximately 60 nm were interestingly formed on the film with horizontal manner of alignment during immersion process. The smallest grain size (29 nm) along (100) orientation was achieve with the alignment of substrate tilt towards 60°. The petals structure has high surface area, is a potential metal oxide nanostructures to be develop for optoelectronic devices and chemical sensors.
