Lead halide perovskites and other metal halide complexes as inorganic capping ligands for colloidal nanocrystals
Dirin, D. N.; Dreyfuss, S.; Bodnarchuk, M. I.; Nedelcu, G.; Papagiorgis, Panagiotis; Itskos, Grigorios; Kovalenko, M. V. (2014)Lead halide perovskites (CH3NH3PbX3, where X = I, Br) and other metal halide complexes (MXn, where M = Pb, Cd, In, Zn, Fe, Bi, Sb) have been studied as inorganic capping ligands for colloidal nanocrystals. We present the ...

Long-Lived Hot Carriers in Formamidinium Lead Iodide Nanocrystals
Papagiorgis, Panagiotis; Protesescu, L.; Kovalenko, M. V.; Othonos, Andreas S.; Itskos, Grigorios (2017)The efficient harvesting of hot carrier energy in semiconductors is typically inhibited by their ultrafast thermalization process. Recently, highly promising experiments reported on the slowdown of the intraband relaxation ...

Optical properties of organic semiconductor blends with near-infrared quantum-dot sensitizers for light harvesting applications
Itskos, Grigorios; Othonos, Andreas S.; Rauch, T.; Tedde, S. F.; Hayden, O.; Kovalenko, M. V.; Heiss, W.; Choulis, Stelios A. (2011)We report an optical investigation of conjugated polymer (P3HT)/fullerene (PCBM) semiconductor blends sensitized by near-infrared absorbing quantum dots (PbS QDs). A systematic series of samples that include pristine, ...
