Abstract
In this study, samples of ZnO doped with Se were prepared using the
biosynthetic method with matoa leaf extract. ZnO samples doped with Se were
made with variations of doping addition. Optical and structural properties were
characterized using UV-Vis Spectroscopy and X-ray Diffraction technique. The
results of UV-Vis spectrophotometer analysis showed an absorption peak at a
wavelength of 300-600 nm. The hexagonal wurtzite crystal structure with nine
diffraction peaks. The effect of the addition of Se doping causes the diffraction
peak to shift to a small 2θ. This Se-doped ZnO sample has the potential to be
applied in solar cell.
