Abstract

Sb2S3 thin films have been prepared using chemical bath deposition .these films were annealed for
different temperatures 373, 473 k. Absorbance and transmittance spectra were recorded in the wavelength range (300-
900) nm. the nature of electronic transitions was determined, it was found that these films have direct allowed transition
with an optical energy gap of 1.72, 1.76, 1.82 eV before and after annealing respectively. the extinction coefficient,
refractive index, real and imaginary part of dielectric constant were also measured before and after annealing.
