تأثير شائبة الفلور على الانتقالات الالكترونية المباشرة لاغشية ZnO

Abstract

ZnO, ZnO: F have been prepared using spray pyrolysis technique.XRD analysis shows that these prepared films were polycrystalline structure. From transmittance and absorption measurement,it has been found that doping cause decrease in transmittance and decreace in the energy gap for direct allowed transition as the percentage of doping increase
