Abstract AR
حضرت أغشية رقيقة لأوكسيد الخارصين (ZnO) بتقنية التبخير الحراري الفراغي على قواعد من الزجاج المرسبة بدرجة حرارة أساس 200° C و بمعدل ترسيب (10 ± 2) nm sec-1 بمعدل تدفق مختلف لغاز الأوكسجين (0.5, 1.0,and 1.5) litter/min., إن حيود الأشعة السينية بينت الغشاء ذو تركيب سداسي متعدد التبلور و الاتجاه السائد هو للمستوى (002).
حددت الخواص البصرية لأوكسيد الخارصين عن طريق النفاذية البصرية باستعمال مطياف ZnO ultra violet – visible لمدى الأطوال الموجية (300-1100) nm فالنفاذية البصرية تتغير من 75% إلى 85% بزيادة معدل تدفق الأوكسجين.
معامل الانكسار لأغشية ZnO تزداد من 1.1 إلى 1.7 بزيادة معدل تدفق الأوكسجين.
Abstract EN
Zinc oxide (ZnO) transparent thin films with different oxygen flow rates (0.5, 1.0, and 1.5) Litter / min.
were prepared by thermal evaporation technique on glass substrate at a temperature of 200℃ with rate (10 ± 2)nm sec-1, The crystallinity and structure of these films were analyzed by X-ray diffraction (XRD).
It exhibits a polycrystalline hexagonal wurtzite structure and the preferred orientation along (002) plane.
The Optical properties of ZnO were determined through the optical transmission method using ulta violet–Visible spectrophotometer with in wave length (300-1100) nm.
The optical transmittance of the ZnO films increases from 75 % to 85 % with increase flow rate of O2, and the optical band gap of ZnO films was found to be increased from (3.0) eV to (3.2) eV with increase flow rate of oxygen.
The refractive index of ZnO flims increased from (1.1) to (1.27) with increase flow rate of O2.
