Doping InP Quantum Dots with Cu+ slows down Hot Electron Cooling
Autor: P. Tim Prins, Freddy T. Rabouw, Dirk A. W. Spruijt, Daniel Vanmaekelbergh, Pieter Geiregat, Celso de Mello Donegá, Zeger Hens
Publikováno v: Proceedings of the nanoGe Fall Meeting 2018.
Nonresonant excitation of colloidal quantum dots (QDs) creates hot carriers that subsequently cool down to the band edges or are trapped in localized states. Carrier cooling and trapping typically happens on timescales from femtoseconds to picosecond

Optical Properties of PbS/CdS Core/Shell Quantum Dots
Autor: Frank Vanhaecke, Karen Van Hoecke, Zeger Hens, Yolanda Justo, Celso de Mello Donegá, Pieter Geiregat
Publikováno v: The Journal of Physical Chemistry C. 117:20171-20177
We determine the optical properties of PbS/CdS core/shell QDs, addressing the energy and the oscillator strength of the first exciton transition and the intrinsic absorption coefficient at short wavelengths. It follows that the intrinsic absorption c
