What is Fabrication of Ultrathin Films with Large Third‐Order Nonlinear Optical Properties about?

## Abstract __An ultrathin composite film containing anionic Ag‐His complexes (His: L‐Histidine) and oppositely charged BH‐PPV was fabricated by means of the electrostatic layer‐by‐layer self‐assembly technique. UV/Vis spectra showed a continuous deposition process of Ag‐His complexes and BH‐PPV. The film structure was characterized by using small‐angle X‐ray diffraction, AFM, and SEM. The nonlinear optical properties of the ultrathin film were studied by using the__ Z__‐scan technique with a laser duration of 8 ns at a wavelength of 532 nm. The film sample exhibited a strong nonlinear saturated absorption, with an__ α~__2__~ __value of −3.9×10__^__−5__^ __m W__^__−1__^ __and a self‐defocusing effect with an__ n~__2__~ __value of −4.78×10__^__−12__^ __m__^__2__^ __W__^__−1__^.
