In-Situ Hydrosilane Reduction and Preparation of Gold Nanoparticles-Gel Glass Composites with Nonlinear Optical Properties

Abstract

Gold nanoparticles (AuNPs)-gel glass composites were prepared by in-situ method on the carboxyl organosilicon oligomer using hydrosilane as reductant. The organosilicon oligomer stabilized the AuNPs and hydrosilane could directly bond to the oligomer after the reducing reaction. The reaction and the samples were characterized by FT-IR spectroscopy, UV-vis absorption spectrometer, UV-vis-NIR transmission spectrometer, TEM, EDS, XPS and SEM. Meanwhile, the nonlinear optical limiting properties of the AuNPs-gel glass composites were investigated through Z-scan technique and optical limiting measurement, which exhibited broadband nonlinear optical limiting properties (532 nm and 1064 nm). This new reductant is a promising candidate for in-situ preparation without extra stabilizing agents or removing of residue byproducts, and the generated particles exhibited uniform size and distribution, providing a new insight into the preparation of metal-polymer nanocomposites.
