Size dependence of the third-order optical nonlinear susceptibility of PbS nanocrystals in PVA
We have synthesized a composite material containing semiconductor nanocrystals with a high third-order optical nonlinear susceptibility chi((3)) (omega) = (6.5 +/- 2.3). 10(-16) m(2)/V-2 (PbS-18nm) at lambda = 1.064 nm in the case where the nanocrystal size approaches the Bohr radius of an exciton in the material.
