Nov 16, 2022The combination of gold nanoclusters (AuNCs) with surface plasmonic metal nanomaterials is an effective and direct method to improve the photoluminescence efficiency of AuNCs. However, the plasmon-enhanced AuNC luminescence strategies usually utilize silica as the separation layer, which requires further functionalization because the silica layer has no

Silica‐Coated Gold Nanorod Supraparticles: A Tunable Platform

Apr 10, 2022Here, we fabricate spherical assemblies – called supraparticles – via a soft-template, solvent evaporation-based method in which an aqueous dispersion of silica-coated gold nanorods (AuSiO 2 NRs) was emulsified in a larger apolar oil phase. The size of the supraparticles was adjusted between 100 nm and 2 m via the water droplet size.

How gold inclusions increase the rate of fluorescein energy

Apr 15, 2010Self-quenching, that limits the luminescence of silica particles containing fluorophores, can be reduced by the presence of gold inclusions within silica. This reduction originates from a dramatic decrease of the non-radiative decay rate, the presence of metal impeding energy transfers to fluorescein quenchers.

Silicon, Silica, Silicates and Silicone

Geochemists also use the term silica to refer to the overall silicon and oxygen content of rocks. This is confusing, but stems from the fact that in rock analysis and sample is dissolved, the solution treated, and the amount of silicon present is determined by precipitating it as silica. So a geologist may say This rock is 48% silica.
