Tuned Wavelengths
Silver nanoplates are surface plasmon resonant (SPR) platelet-shaped nanoparticles that have extremely large absorbing and scattering cross-sections across the visible and near-IR regions of the spectrum. By precisely controlling the plate diameter and thickness, the nanoplate's optical resonance can be tuned to peak at specific wavelengths (550 nm-1000 nm). Learn more
Engineered for the Infrared
Gold nanoshells are nanoscale silica cores that are surrounded by an ultra-thin gold shell. The gold nanoshells can be tuned to strongly absorb or scatter light at any wavelength in the visible and near-IR regions of the electromagnetic spectrum. Learn more
Your Choice of Solvent
Our dried silver nanopowders are formulated with polymer or alkanethiol surface coatings which allow the nanoparticles to easily be redispersed as unagglomerated dispersions in a variety of solvents. We have verified the redispersion with transmission electron microscopy (TEM), UV-visible spectroscopy and dynamic light scattering.
