New optical Nonlinear material based upon PVA with PbS quantum dots
High third-order nonlinear optical susceptibility (chi((3))(omega; omega, -omega, omega) = -4,2 x 10(-16)(m(2)/V-2)). In the visible spectral range may be achieved in PVA composites containing narrow bad gap PbS semiconductor nanocrystals with a strong limitation of the area of charge carrier delocalization.
