| Abstract | ||
| In this research, the structural and optical properties were studied for Bi2O3 and Bi2O3: Al thin films with different doping ratios ( 1, 2, 3 ) % , which were prepared by thermal evaporation technique under vacuum , with thickness ( 450 ± 20 ) nm deposited on glass substrates at room temperature ( 300 ) K , Structural measurements by ( XRD) techniques demonstrated that all samples prepared have polycrystalline structure with tetragonal structure and a preferred orientation [ 201 ] the optical measurement shows that all films have a direct energy gap , and in general decrease with the increase of doping ratio except ratio ( 3% Al ) . The optical constant such as absorption coefficient , extinction coefficient , refractive index real and imaginary parts of the dielectric constant and optical conductivity were calculated before and after doping with the range of wave lengths ( 300 - 1100 ) nm . | ||
