摘要：

PbS-bearing Langmuir-Blodgett (LB) films were synthesized by alternating the processes of sulfidation by the exposure to H2S gas and intercalation of pb(2+) 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, ((3)(chi)), 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 ((3)(chi)) values of the order of 10(-12) esu, and the in situ growth of the quatum-state PbS resulted in the enhacement of ((3)(chi)).
