DOI: 10.1021/jacs.0c10557
Abstract: Single-wall carbon nanotubes (SWCNTs) in liquid suspension have been observed to emit delayed, microsecond-scale fluorescence arising from upconverted triplet excitons that are directly created through energy transfer from singlet oxygen molecules (1O2). The singlet oxygen… read more here.

DOI: 10.1039/c8ta10037c
Abstract: Organic materials containing heavy atoms have been used in photovoltaics to overcome a fundamental limitation: short exciton diffusion length (LD). We highlight studies showing increased LD in solar cells using triplet-generating materials and tackle challenges… read more here.

DOI: 10.1063/5.0035217
Abstract: Triplet excitons in organic materials are nonradiative and tightly bound as self-trapped ones due to the strong electron-lattice coupling. They exhibit a finite radius and long lifetime and so can be regarded as the isolated… read more here.
