The impact of an electric field on the energy transfer between Fir6 and rubrene in the PL process of the PVK:Fir6:rubrene films was explored by steady-state PL spectra in electric field and electric field modulated transient PL spectra.
Compared to the common resonance energy transfer process, the PRET system in this paper excites the acceptor through a longer-lived triplet state, and thus the phosphorescence lifetime of the guest that is in the doped system is greatly increased.
The strong three-photon excited phosphorescence enables NPFA-2%PorPt NPs to be successfully applied for in vivo time-resolved brain and muscle vascular imaging with deep penetration, high spatial resolution, and contrast, and even the small capillaries in the deep tissue can be recognized.
This work demonstrates a photoreversible fluorescence and room-temperature phosphorescence switching based on a photo-controlled triplet-to-singlet Förster resonance energy transfer.
