Zone‐Sectored Organic Crystals with Spatially Resolved Exciton Dynamics Open
Among the organic semiconductors, rubrene stands out in terms of hole mobility, luminescence yield and exciton migration distance. A novel type of rubrene microcrystal is prepared in the orthorhombic phase, exhibiting zone‐sectored tabular…
Having a good vibe: strong coupling to the electronic system creates incoherent and coherent phonons in 1L-TMDCs Open
The electronic dynamics in monolayer transition metal dichalcogenides (1L-TMDCs) following optical excitation crucially determine all their optoelectronic applications. The basic processes can be divided into energy redistribution leading …
Strong quenching of dye fluorescence in monomeric perylene orange/TMDC hybrid structures Open
Hybrid structures of TMDCs and monomers of the perylene diimide dye perylene orange (PO) exhibit charge transfer after optical excitation. This results in drastic PO fluorescence quenching and may be exploited in optoelectronic devices.
