The growth of nanocrystallinePbS films by chemical bath (CB) onto glass at a temperature T = 40 ± 2°C is reported. The morphological changes of the layers were analyzed by Atomic Force Microscopy.X-ray diffraction spectra displayed peaks at 2θ = (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 ~32 nm, whereas with the doped sample was 25-15 nm.In optical absorption, forbidden band gap energy shift disclose a shift in the range 1.2-2.0 eV.
