Face-centered cubic and hexagonal closed packed nanocrystal superlattices of gold nanoparticles prepared by different methods

Article Abstract:

The organization of dodecanethiol- stabilized Au nanoparticles prepared by two different synthetic routes into nanocrystal superlattices with different packing structures despite similarity in nanoparticle size is demonstrated. Findings stated that Au nanoparticles obtained by bulk gold vaporization (SMAD procedure) has primarily defective core structures, lack faceting and behave like hard spheres.

Investigations on nanoparticle-chromophore and interchromophore interactions in pyrene-capped gold nanoparticles

Article Abstract:

Pyrene chromophores functionalized to gold nanoparticles using methylene groups of varying chain length were prepared. A detailed investigation was conducted on the nanoparticle-chromophore and interchromophore interactions. The emission spectra studies indicated that the local environment close to the surface of Au nanoparticle was more polar compared to the bulk medium.

3-methylthiophene self-assembled monolayers on planar and nanoparticles Au surfaces

Article Abstract:

The adsorption of 3-methylthiophene on planar and nanoparticle Au surfaces is investigated. The resulting systems are compared with a benchmark system based on 1-decanethiol.
