الانتقالات الالكترونية المباشرة لاغشية اوكسيد الكادميوم المحضرة بطريقة الرش الكيميائي الحراري

Abstract

Thin films of CdO with thickness 0.3 µm have been prepared on a borosilicate
glass substrate using chemical spray pyrolysis technique. The results indicate
that the as deposited thin films have a direct transitions with allowed and
forbidden energy gap equal 2.42 and 1.9 eV respectively. The as deposited
thin films were polycrystalline in structure and that the preparation conditions
affected the nature of structure in comparison with the literature survey , it
becomes more crystalline .
