that efficient RET to MG is indeed possible using CNP donors. We also consider simple assemblies of the CNPs tethered to plasmonic nanoparticles, which could be experimentally realized using DNA templating, and we show that strong coupling between the CNPs and the plasmonic nanoparticles may be realized under experimentally feasible geometries. Our results suggest that these CNPs show exceptional promise as RET donors and as building blocks for assemblies that can realize strong coupling between light and matter.
