Abstract AR

في هذا البحث، تم تحضير غشاء أوكسيد النحاس بطريقه الرش الكيميائي الحراري باستخدام تراكيز مختلفة من المحلول المائي لملح كلوريد النحاس.

حددت الخصائص التركيبة و البصرية للأغشية المحضرة باستخدام حيود الأشعة السينية و التحليل الطيفي للأشعة المرئية و فوق البنفسجية.

تبين من نموذج حيود الأشعة السينية أن الأغشية ذات تركيب أحادي و متعدد التبلور عند الاتجاهية البلورية (111-) و (111) .

حددت فجوه الطاقة (2.42-2.05 e V) و معامل الامتصاص عالي يتراوح بين 1-3*105 - 1*105) cm) عند تركيز 0.3M و معامل الخمود يتراوح بين (0.7 - 0.85).

وجد أن هذه الثوابت ذات طبيعيه متذبذبة و التي تعزى إلى طبيعة الأغشية من حيث التركيب و التركيز.

Abstract EN

In this work, CuO thin films were prepared by spray pyrolysis method using different concentration of CuCl2 .2H2O.

X- ray diffraction (XRD) and UV-VIS transmission spectroscopy were employed to characterize the structure and optical properties of prepared films.XRD patterns show that the films are polycrystalline and monoclinic with (-111) and (111) crystalline orientations.

The optical band gaps (2.05 to2.42eV) ,with high absorption coefficient change from (3*105 - 1*105) cm-1 at 0.3M concentration , and excitation coefficient change from (0.85 – 0.7).

These constants are found to be oscillatory in nature, which are attributed to the particular structure of films and their concentration.
