Concentration and excitation effects on the exciton dynamics of poly(3-hexylthiophene)/PbS quantum dot blend films
Tsokkou, Demetra; Itskos, Grigorios; Choulis, Stelios A.; Yarema, M.; Heiss, W.; Othonos, Andreas S. (2013)The dynamics of photoexcitations in hybrid blends of poly(3-hexylthiophene) (P3HT) conjugated polymer donor and oleic-acid capped lead sulfide (PbS) quantum dot (QD) acceptors of different concentrations - for light ...

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, ...
