Study and Characterization of Non- linear Optical Properties of ZnS nanobelts

Nada Abdul Hadi Kareem

Abstract


In this work, first we synthesized the nanobelts semiconductor ((ZnS manufactured through a chemical evaporation deposition (CVD). the films obtained diagnosed through x-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscope (SEM), was a study of non-linear optical properties. in comparison with the optical microscope, confocal microscope optical measurements, measurements of second harmonic generation  using Ti : Sappire laser femto second (800nm), showed that nanobelts ZnS prepared, had a  Blue emission at a wavelength 400 nm, which can be attributed to the deep-level emissions resulting from defects or impurities.
