Self-assembled, ordered gold nanocrystal/silica thin films for prism-based surface plasmon resonance sensors.

Conference ·
OSTI ID:965107
Gold nanocrystal(NC)/silica films are synthesized through self-assembly of water-soluble gold nanocrystal micelles and silica by sol-gel processing. Absorption and transmission spectra show a strong surface plasmon resonance absorption peak at {approx}520 nm. Angular excitation spectra of surface plasmon show a steep dip in the reflectivity curve at {approx}65{sup o} depending on the thickness and refractive index of the gold NC/silica film. A potential SPR sensor with enhanced sensitivities can be realized based on these gold NC/silica films.
