Abstract
PbSe thin films were deposited on glass substrate by chemical bath deposition (CBD) technique from the aqueous solutions of lead acetate, selenium sulphate, ammonia, in which ethylene di-amine tetra acetate (EDTA) was employed as complexing agent. The grown films were optically characterized using M501 Single Beam Scanning UV/VIS Spectrophotometer. The result shows that the film has high absorbance in almost regions of electromagnetic spectra with low transmittance and reflectance values in these regions. The calculated value of the film thickness was found to be 1.11285-1.19536m. This film thickness was also found to depend on the dip time and concentration of EDTA used. The PbSe thin film was found to have band gap energy of 1.0eV, and with high absorption coefficient obtained.
