For comparison, indicators of RET efficiency are also computed for MG adsorbed to other RET donors, including lone silver, gold, and platinum nanoparticles (see Supporting Information, Figures and). Like the CNPs, the gold nanoparticle has a resonance with relatively strong spectral overlap with the absorption resonances of MG. On the other hand, the silver nanoparticle has a resonance that is 1 eV blueshifted (at 3.1 eV) and the platinum nanoparticle has a broad spectral feature that peaks at 4.5 eV. As can be seen in Table , the RET transfer efficiency, η, is smaller for silver and gold donors than for the CNP400 system. Coupling to lone metal nanoparticle donors, including gold (Figure ) or silver (Figure ) leads to enhancement in scattering and population transfer, but the effects are considerably weaker as compared to these effects when MG is coupled to the CNPs. Coupling to the lone plasmonic systems leads to roughly a 10-fold increase in population transfer: a final sink state population of 2.0×10 -4 and 2.2×10 -4 is observed for the Au-MG and Ag-MG systems, respectively. (see Figures , and Table ). We also consider RET to MG from a 5 nm platinum particle, which exhibits a very broad spectral feature in the UV range (see Figure in the SI). Again we observe substantially lower RET efficiency in this system when compared to the CNPs decorated with the platinum nanospheres of the same size. We note that, because of the broadness of the absorption feature in the platinum nanoparticle, a shorter pulse (1.81 fs) was used for the lone platinum simulations. Because the illumination conditions were different for the lone platinum system, direct comparisons of the RET efficiency to other systems are not possible.
