N2 - Zinc oxide (ZnO) is one of the semiconductor oxides compounds that have played an important role in various strategic applications including solar cell, sensor, biomedical and photocatalysis. This study investigated the effect of ZnO crystallite size on its optical properties. It was specifically aimed at demonstrating the correlation between the crystallite size and bandgap energy value and how they affected the functional performance of the semiconductor oxide. This was carried out using various ZnO samples with nano and micrometer sizes. In addition to the commercially available micrometer samples, ball-mill treatments with 10 and 20 Hz frequency were carried out to provide more variation in micrometer size for the samples. All samples were characterized by x-ray diffraction (XRD) and ultraviolet-visible (UV-Vis) spectroscopy. The results obtained from the investigation showed that ZnO sample with 20 Hz frequency ball-mill treatment had the largest crystallite size of 85.06 nm and the smallest bandgap energy value of 3.16 eV. Meanwhile, the ZnO samples in nanometer range provided the smallest crystallite size of 22.34 nm and the largest bandgap energy value of 3.25 eV. The availability of ZnO samples of different crystallite sizes and their well-known bandgap energy values can be potentially used for the above-mentioned applications.
