Facile Synthesis of Zinc Oxide Nanorods Using a Single-Phase Flow with 3D Printed Device

Abstract

In this work, the single-phase flow chip was applied to synthesize ZnO nanomaterial. The facile process of synthesizing ZnO can be achieved through the printed single-flow chip with the Y-junction pattern. The flow chip was designed and printed with a stereolithography 3d printer. Then, the physical properties of prepared ZnO were performed with an X-ray diffractometer (XRD), Fourier Transform Infrared spectrometer (FTIR), scanning electron microscope (SEM), and UV-visible near-infrared spectrophotometer (UV-Vis-NIR), respectively. It was found that the prepared ZnO exhibited a hexagonal wurtzite structure with the morphologies of ZnO powders, showing the nanorod structure with rod length in micron size. The influence of precursor flow rate on the properties of ZnO nanorods was evaluated. The UV photodetector has been fabricated on a plastic print circuit board with an interdigitated electrode. The optimized sensitivity of the fabricated UV photodetector was investigated.
