    STUDI SIFAT OPTIK DAN MORFOLOGI PERMUKAAN SAMPEL BIOSINTESIS ZnO DOPING SELENIUM
    (Elfitra, 2023-03) Sonia, Windi; Rini, Ari Sulistyo
    Synthesis of selenium doped ZnO (ZnO/Se) has been successfully carried out. In this study, selenium ZnO doping was prepared by the biosynthesis method using matoa leaf extract. optical properties and surface morphology of ZnO/Se were analyzed using UV-Vis spectroscopy characterization and Field Emission Scanning Electron Microscopy (FESEM). The UV-Vis spectroscopy results show that the absorption peak is in the optical range of 300-700 nm with a decreasing bandgap energy. FESEM analysis showed image magnification of up to 20,000 times with nanoflower morphology
