چکیده
|
Tunable local surface plasmon resonance (lspr) enhancement properties of scaffold-based multi-nanoparitcle clusters were investigated using finite-difference time-domain (fdtd) method with calculated optical spectra, near-field distribution, and average enhancement of hybrid nanostructures as slab/nanoparticls, cylinder/nanoparticles, and sphere/nanoparticles. focusing on influence factors including surface curvature, coupling effect, and decorated particle number, several models were built for further understanding on the dominate contribution in complicate multi-particle nanostructure and to explore their potential for plasmonic enhancement applications such as surface-enhanced raman spectroscopy (sers), solar cells material, lspr sensor, and nanoantenna.
