For larger nanoparticles (≥ 5 nm) with a well-developed plasmon absorption, the effect of plasmon-plasmon interactions on the absorption of a group of nanoparticles has been calculated (see refs 28 and 30). For example, with four 10-nm diameter particles arranged in a tetrahedron, a splitting of the peak or broadening between 510 and 530 nm is predicted. Since the theoretical picture of plasmon-plasmon interactions does not strictly apply to small nanoparticles (≤ 5 nm) for which the plasmon absorption is suppressed, a direct comparison with our experiment is not possible. However, the enhancement that we observe upon nanoparticle aggregate formation does lie in the expected spectral region near 520 nm.
