Controlling of ZnO nanostructures by solute concentrationand its effect on growth, structural and optical properties

TL;DR

This study investigates how varying solute concentration in chemical bath deposition influences the morphology, structure, and optical properties of ZnO nanostructures, enabling controlled synthesis of nano-needles and rods.

Contribution

It demonstrates that solute concentration can be used to control ZnO nanostructure morphology during chemical bath deposition without advanced equipment.

Findings

Solute concentration affects ZnO nanostructure shape and size.

Controlled morphologies include nano-needles and rods.

The method is simple and does not require high-pressure or microwave assistance.

Abstract

ZnO nanostructured films were prepared by chemical bath deposition method on glass substrates without any assistance of either microwave or high pressure autoclaves. The effect of solute concentration on the pure wurtzite ZnO nanostructure morphologies is studied. The controlling of the solute concentration help to control nano-structure in the form of nano-needles, and rods.
