Abstract
The synthesis of microwave-assisted ZnO nanoparticles at a power of 540 Watts has
been successfully carried out. The formation of ZnO was prepared using a
biosynthesis method with Matoa leaf extract. In this study, ZnO samples were
analyzed for their optical absorption properties and crystal structure. The results of
UV-Vis spectrophotometry analysis showed that there was an absorbance peak in the
range of 300-800. Crystal structure analysis on XRD described seven characteristic
peaks with a wurtzite crystal structure where the highest peak was in the plane (101).
This ZnO sample has the potential to be applied as a photocatalyst or solar cell
material.
