Relaxation luminescent conjugated polymers

Time-resolved photoluminescence spectroscopy has emerged as one of the most important tools for studying the properties of solid-state materials suited to optoelectronic applications, including semiconducting polymers. This is due to the relatively direct information about the excitation dynamics, such as recombination and relaxation processes, which is obtained from such experiments. Wong et al. [1232] have reported a luminescence lifetime much smaller than 1 ns in conjugated polymers and have pointed out that nonradiative as well as bimolecular processes might play an important role. Furukawa et al. [1233] have studied time-resolved luminescence in PPV and have explained the re-...
