Sizing morphology-controlled gold nanoparticles by linear absorption spectroscopy.

ORAL

Abstract

The most remarkable optical property of gold nanoparticles is surface plasmon resonance (SPR) which dramatically differs from its bulk counterpart. Within the frame of Mie theory, we investigated the relationship between the size and the SPR and its corresponding bandwidth. An empirical fitting function will be given for the sizing curve for morphology-controlled gold nanoparticles in water and possible physical mechanisms for the size-dependent optical properties will be discussed in this paper.
