Research paperExperimental CharacterizationComputational DFTAtomistic Origin of Photoluminescence Quenching in Colloidal MoS₂ and WS₂ NanoplateletsSurender Kumar, Markus Fröhlich, Stefan Velja, Marco Kögel et al.arXiv·2026·10.5281/zenodo.17661456·arXiv:2511.19077AbstractCombining femtosecond transient absorption spectroscopy with first-principles calculations on MoS₂ and WS₂ nanoplatelets, the paper identifies edge-localized optically bright hole traps as the origin of sub-picosecond exciton decay and photoluminescence quenching in colloidal TMD nanoplatelets. The study compares nanoplatelets and larger nanosheets, examines size-dependent optical shifts, and shows that edge states persist under sulfur-terminated and hydrogen-passivated conditions.Read more
