Abstract
PbS-bearing Langmuir-Blodgett (LB) films were synthesized by alternating the processes of sulfidation by the exposure to H2S gas and intercalation of Pb2+ ions. These processes allowed the in situ formation and growth of the nano-sized (quantum-state) PbS in the hydrophilic interlayers of the stearate LB film. The third-order nonlinear optical susceptibility, χ(3) of the quantum-state PbS embedded in the LB matrix was evaluated for the first time by third harmonic generation. The PbS/LB films showed the χ(3) values of the order of 10-12 esu, and the in situ growth of the quatum-state PbS resulted in the enhacement of χ(3).
