The integrated photoluminescence intensity in thin films of 'Super Yellow' copolymer has been analyzed using a Mott-like temperature dependence. This has enabled us to observe contributions from two emission channels, indicative of exciton recombinat...

The contribution of triplet-triplet annihilation to the lifetime and efficiency of fluorescent polymer organic light emitting diodes (2011)
Journal Article
King, S., Cass, M., Pintani, M., Coward, C., Dias, F., Monkman, A., & Roberts, M. (2011). The contribution of triplet-triplet annihilation to the lifetime and efficiency of fluorescent polymer organic light emitting diodes. Journal of Applied Physics, 109(7), Article 074502. https://doi.org/10.1063/1.3561430

We demonstrate that the fast initial decay of a prototypical fluorescent polymer based organic light emitting diode device is related to the contribution that triplet-triplet annihilation makes to the device efficiency. We show that, during typical o... Read More about The contribution of triplet-triplet annihilation to the lifetime and efficiency of fluorescent polymer organic light emitting diodes.

Long range energy transfer in conjugated polymer sequential bilayers (2011)
Journal Article
