Nonradiative energy transfer in mixed Langmuir monolayers and Langmuir–Blodgett films of compounds of different chemical composition and structure
- 24 Downloads
The efficiency of the Förster resonance energy transfer (FRET) in a monolayer film containing the energy donor and energy acceptor fluorophores is low since the energy transfer process occurs in one plane only. As the number of layers increases to five, the energy transfer efficiency increases due to the interlayer energy transfer occurring in three dimensions. Further increase in the number of layers (up to 10) causes no significant increase in the efficiency since in this case the total film thickness exceeds an optimum value for the FRET process.
