Abstract :
An ultrathin composite film containing both poly(diallyldimethyl ammonium chloride) (PDDA) and hexa(sulfobutyl)fullerenes (C60-HS) has been fabricated by the electrostatic layer-by-layer self-assembly technique. UV–Vis spectra showed a continuous deposition process of PDDA and C60-HS. The film structure was characterized by small angle X-ray diffraction measurement and AFM image. The nanothick film showed an effective third-order nonlinear refractive index n2=1.56×10−8 esu.
