Abstract

It is well known that the properties of nanostructured materials are not only dependent on the size and the function of the individual nanoparticles itself, but also the interparticle distances and interactions. Recently our group reported a solid phase exchange reaction to synthesize gold nanoparticles with a single carboxyl functional group on the surface. Using these monofunctional gold nanoparticles, we synthesized a nanoparticle-polymer hybrid material with a necklace structure using a single step chemical reaction. The optical limiting performance of the gold nanoparticles-polymer hybrid was then investigated using a 4.1 ns laser at 532 nm. The hybrid materials exhibited enhanced optical limiting properties compared to individual monofunctional gold nanoparticles due to the dipole-dipole interparticles interactions. It was also found that the triplet excited state absorption was the main contribution to the optical limiting properties of the nanoparticles/polymer hybrid materials.
