Following the work by Chuang et al., we first developed a more specific model for our 2D (NPLs) to 0D (QDs) energy transfer system, which takes the scale of donor-acceptor distances and the actual geometry of the dipole distribution into consideration. Briefly, the relatively small HgTe QD is modeled as one single dipole, while the larger HgTe NPL consists of multiple dipoles (Figure ). The FRET rate equation is determined by calculating the summation of dipole-dipole coupling of donor-acceptor pairs over all possible dipole orientations (see Supporting Information for details). The summation can be calculated as a continuous integration to extract the distance dependence:
