Abstract
ZnO nanoparticles have been prepared through a biosynthetic method using microwave method
with the addition of sulfur doping with percentage variations of 1 and 2%. Sulfur doping ZnO
particles in the form of flakes from synthesis were characterized using UV-Vis spectroscopy
and x-ray diffraction (XRD). The UV-Vis absorption spectrum shows absorption peaks in the
UV region of 300-400 nm with bandgap energy ranging from 3.04-3.08 eV. XRD analysis
exhibit the crystal size is in the range of 33 nm. The emerging plane peaks in the 30-80° angle
range confirm wurtzite-shaped crystals with high purity of ZnO particles
