The growth of nanocrystalline PbS films by chemical bath deposition （CBD） onto glass at temperatureT = 40 ± 2℃, is presented in this research. We report on the modification of structural, optical nanostructures due to in situ *** morphological changes of the layers were analyzed using AFM. XRD spectra displayed peaks at 20 = （26.00, 30.07, 43.10, 51.00, 53.48）, indicating growth on the zinc blende face. The grain size determined by x-rays diffraction of the undoped samples, was found -36 nm, whereas with the doped sample was 32-23 nm. Optical absorption, transition direct and indirect the forbidden band gap energy （Eg） shifts discloses a shift in the range 1.45-2.4 eV.
