Extinction, emission, and scattering spectroscopy of 5-50 nm citrate-coated gold nanoparticles: An argument for curvature effects on aggregation
文摘
Complementary extinction, emission, and dynamic light scattering study Aggregation observed for 5–10 nm CT-GNPs but not for 30–50 nm CT-GNPs at pH 6.0–6.5 30–50 nm CT-GNPs behaved primarily as light scatterers. 5–10 nm CT-GNPs exhibited extinction/emission properties. Surface curvature affected citrate corona shielding of 5–10 nm CT-GNPs.
