PbS nanocrystalline thin films were prepared by Chemical Bath Deposition CBD technique. A comparative study between standard and nanocrystalline PbS thin films was performed. We denoted standard the PbS film with a good photosensitivity for to use as IR detector. This film was deposited after 1 hour from chemical bath containing reducing agent and Bi ions as doping clement. The nanocrystalline film was obtained at shorter reaction time after 17 minutes from reducing bath without doping element. The other parameters concentration of the reactants, pH, temperature were kept constant for the all depositions.
