Spectrophotometric measurements in Vis-UV range have showed that all the films have a high transmission of the extent of wavelengths (200-800 nm) about 85% in the visible zone with a band gap energy ranged in ( 3.28 -3.21 ) eV. The addition in doping concentration leads to light deviation of bandsThesis
