Delayed fluorescence as a probe of radiationless transitions in anthracene and algae
… is qualitatively explained in terms of triplet exciton traps. The delayed fluorescence emitted by algae is explained in terms of a triplet exciton fusion model in which the production of triplets is mediated by a photochemical reaction center (photosystem II). The evidence for this model is …

Charge and energy transport in 0D/2D systems probed using linear and nonlinear spectroscopy
… of QDs and TMDs. The remainder explores exciton dynamics and transport in these low-dimensional semiconductor systems. In Chapter 2, low temperature spectroscopy and time-resolved photoluminescence spectroscopy are used to probe the complex energy landscape seen by excitons in …

Photochemical Tailoring of Single-Wall Carbon Nanotubes by Photoexcited Sodium Hypochlorite
Single-wall carbon nanotubes (SWCNTs) are intriguing 1D nanomaterials whose unusual electronic properties are of interest for a wide array of applications. More specifically, semiconducting SWCNTs have structure-specific electronic transitions that allow for discrete near-infrared fluorescence …
