Mechanisms of triplet energy transfer across the inorganic nanocrystal/organic molecule interface
Nature Communications, 11(1).
TL;DR:
Combined transient absorption and photoluminescence measurements are performed on model systems comprising lead halide perovskite nanocrystal/polyacenes which either favour or prohibit charge transfer as the triplet acceptors, finding triplet energy transfer proceeds via a charge separated state.
