ABSTRACT
Zinc oxide (ZnO) synthesis using natural bioreductants has attracted the attention
of many researchers because it is environmentally friendly and non-toxic. In this
study, ZnO synthesis was carried out using sandoricum koetjape peel extract as
biological reduction agent from its precursor (zinc nitrate hexahydrate) at the
temperature of 60° for 2 hours. The as-prepared ZnO samples were then annealed
with different temperature 300°C, 400°C, and 500°C for 1 hours. Crystal
properties, morphology, optical properties, and functional groups of samples were
characterized using X-Ray Diffraction (XRD) spectroscopy, Scanning Electron
Microscopy (SEM), UV-Vis Spectroscopy, and Fourier Transform Infared
(FTIR). The X-ray diffraction peak shows that the ZnO sample has a hexagonal
wurtzite structure where the crystal size increases with increasing annealing
temperature. The results of SEM analysis obtained microspherical particles with
the smallest size of 750.4 nm in the sample with annealing temperature of 500°C,
and the largest size of 840 nm in the sample without annealing. The UV-Vis
spectrum shows the optical absorption peak in the wavelength range of 350-380
nm in all samples with a band gap energy of 3.04 eV to 3.28 eV. The chemical
bond formation of ZnO was confirmed by FT-IR analysis at a wave number of
500-4500 cm-1. It can be concluded that the annealing process on ZnO samples
can affect the crystalline properties of the samples, crystal size, morphology and
band gap energy of ZnO.
