Abstract

Zinc oxide (ZnO) micro and nanorods were successfully prepared using Pandanus amaryllifolius and hexamethylenetetramine (HMTA) separately as stabilizers using the solution immersion method. Two types of ZnO seed layer were prepared using the same pre-cursor with the different stabilizers. The fabricated ZnO microrods exhibit absorption at ~375 nm as revealed from the UV–Visible absorption spectrum, and this is comparable with ZnO nanorods synthesized using HMTA. X-ray diffraction (XRD) measurement displayed a sharp peak corresponding to the hexagonal wurtzite structure of ZnO microrods. Field emission scanning electron microscopy (FESEM) of ZnO microrods showed average diameter at approximately 500 nm compared to 70 nm of those synthesized from HMTA. A new finding is the ability of Pandanus amaryllifolius as a green stabilizer to grow a dense ZnO microrod structure with high crystallinity. Results reveal that both samples from different stabilizers during the preparation of the ZnO seed layer greatly improved the morphological and structural properties and optical absorption of ZnO. The main outcomes from this study will benefit optoelectronic application, such as in ultraviolet (UV) sensors.

Summary

Introduction

A high yield of zinc oxide (ZnO) nanostructures, using energy-efficient and cost-effective synthesis, has been preferred by various industries such as optoelectronics, photocatalytic, biomedical, agriculture, etc. This demand has led to a progressive synthesis method of ZnO nanostructures. The synthesis method has evolved towards a greener approach, such as the solution immersion method, which mostly uses hexamethylenetetramine (HMTA) as a stabilizer. This stabilizer is water-soluble, and the waste can be thrown away. As an alternative to these conventional chemical and physical methods, there is tremendous progress in the synthesis of nanostructures by using plant-mediated synthesis as reported by the literature
