Abstract
We report on the resonant plasmon enhancement Raman scattering (RS), photoluminescence (PL), and IR absorption by colloidal CdSe-based nanocrystals deposited on Au nanodisk and nanoantenna arrays. Numerical simulations were applied to calculate structural parameters of nanodisks and nanoantennas for which local surface plasmon resonance (LSPR) energy coincides with interband transition energies and surface optical (SO) phonon energies in NCs, correspondingly. The enhancement factors of RS and PL depend resonantly on the nanodisk size. Tip-Enhanced Raman Scattering (TERS) imaging allowed us to carry out the local spectral analysis of CdSe NCs with nanometer spatial resolution. A design of H-type nanoantennas was chosen to achieve maximal enhanced absorption by SO phonons from 1 monolayer of NCs.
