دراسة الانتقالات الالكترونية والخواص البصرية لاغشية اوكسيد النحاس المشوب بالانديوم بطريقة الترسيب الكيميائي الحراري

Thin films of copper oxide and CuO:In were prepared using chemical spray technique on borosilicate glass bases at temperature about (623k)with doping ratios(1-5)%. The transmission and absorption spectra in the spectral range (300-900) nm, Were reccorded for prepared thin films. The optical and structural properties were studied, the results ofxro showed That all The prepared films were polycrystalline with monoclinic structure with no effect of doping on them. The optical properties which had been under investigation were the absorption coefficient, forbidden energy gap, reflectance, extinction coefficient, refractive index, dielectric constant in its two parts and conductivity were calculated with photon energy, and we found the electronic transition for these films to be direct allowed only
