A strange quantum effect dramatically boosts energy transfer
Researchers have discovered a mechanism called proton shuttle-assisted triplet energy transfer (PS-TET) that significantly improves energy transfer efficiency. By using a proton shuttle, the process accelerates energy movement between quantum dots and molecular acceptors.
Electron and proton motion often work together in both living systems and engineered materials. The most familiar example is proton-coupled electron transfer (PCET), a process that plays a central role in bioenergetics, cellular respiration, photosynthesis, and nitrogen fixation. PCET has also influenced the design of many artificial materials used for energy conversion and storage. More recently, scientists identified another related process known as proton-coupled singlet energy transfer (PCEnT).
