We first consider the case in which the RET acceptor, MG, is adsorbed to a CNP RET donor (either CNP400 or CNP600). Specifically, MG is modeled as being adsorbed to the small metal nanoparticle constituent of the CNP. Unless otherwise indicated, we excite the system with a short (3.62 fs) pulse centered at 2.02 eV with a peak field strength of 5.14•10 7 V/m. The center frequency of this pulse was chosen to overlap with the absorption resonances in MG, and the short pulse duration leads to a broad energy distribution spanning the visible and near-UV range, which is the energy range over which the nanostructures studied here have strong resonant properties.
