From using X-Ray diffraction (XRD) pattern, all the prepared films have hexagonal wurtizite structure. Transmittance and absorbance were estimated via Uv-Visible spectrophotometer. Parameters of optical (energy gap, absorption coefficient, refractive index, extinction coefficient, real and imaginary parts of dielectric constant) were calculated from recording absorption spectrum. The energy gap of (ZnO) films had been seen as decreased with increasing concentration of bismuth. Keyphrases: (ZnO: Bi) films, Optical constants, XRD, chemical pyrolysis technique
