Exciton transition energies and temperature dependence of ultrafast relaxation processes have been investigated in polydiaca tylene (PDA-( 12,8)) Langmuir-Blodgett films with several exciton transition energies using femtoseeond absorption speetroscopy. The relaxation from self-trapped exciton to th
Excitation energy relaxation ofN,N'-dioctadecylrhodamine B incorporated in Langmuir-Blodgett monolayers has been studied with a picosecond time-resolved fluorescence spectrophotometer. Relaxation of singlet excitation energy in a monomolecular layer was interpreted in terms of ( 1 ) energy migration
