Abstract AR
حضرت أغشية رقيقة لأكسيد الخارصين ZnO بتقنية التبخير الحراري الفراغي على قواعد من الزجاج بدرجة حرارة أساس 200 C° و بمعدل ترسيب nm sec-1 (2±10) لسمك مختلف من (220 إلى 420) nm 15 ± nm, إن حيود الأشعة السينية بينت أن الأغشية ذو تركيب متعدد التبلور و الاتجاه السائد هو للمستوى (002).
حددت الخواص البصرية ?وكسيد الخارصين عن طريق النفاذية البصرية باستعمال مطياف Ultra Violet – Visible ضمن الأطوال الموجية (300-110) nm و كانت قيمة فجوة الطاقة البصرية للأغشية تتراوح بين (2.9) ev إلى (3.1) ev بزيادة سمك الغشاء.
Abstract EN
Zinc Oxide transparent thin films (ZnO) with different thickness from (220 to 420)nm ±15nm were prepared by thermal evaporation technique onto glass substrates at 200 with the deposition rate of (10 2) nm sec-1, X-ray diffraction patterns confirm the proper phase formation of the material.
The investigation of (XRD) indicates that the (ZnO) film is polycrystalline type of Hexagonal and the preferred orientation along (002) plane.
The Optical properties of ZnO were determined through the optical transmission method using ultraviolet- visible spectrophotometer with wavelength (300–1100) nm.
The optical band gap values of ZnO thin films were slightly increased from (2.9-3.1) eV as the film thickness increased.
