Improvement in Photostability of Fluorescein by Lanthanide Ions Based on Energy Transfer-based Triplet State Quenching
Photobleaching of fluorophores is a big obstacle in their advanced application in various systems. Since many photobleaching pathways originate from the long-lifetime triplet (T-1) state, shortening the lifetime of the T-1 state is a rational strategy to enhance the photostability of the fluorophores. In this study, we observed that some lanthanide ions promoted the photostability of fluorophores by quenching the T-1 state via the triplet-triplet energy transfer from the fluorophore to the lanthanide ions.
