Polarons OLEDs

Indeed, spin statistics mandate that if the rates of reactions (1) and (2) are the same, then the nongeminate polaron pairs generated by carrier injection in OLEDs would yield 3 TEs for every SE. This SE/TE branching ratio is one of the most important factors suppressing the efficiency of OLEDs based on the fluorescent decay of SEs. However, recent studies suggest that in luminescent -conjugated polymers the rate of reaction (1) is higher than that of (2), so the yield of SEs is... [Pg.8]

The foregoing section attempted to provide an introduction to the dynamics of singlet excitons, generated either by photoexcitation or by polaron recombination, and the effects of polarons and TEs on the SE dynamics. We now turn to the basic structure and dynamics of OLEDs, which obviously reflect the basic processes described above. [Pg.9]
