Optical fiber amplifiers based on PbS/CdS QDs modified by polymers.
Opt. Express 21(7) , 8214-9, (2013) Optical fiber amplifiers based on PbS/CdS semiconductor quantum dots (QDs) modified by an amphiphilic polymer were demonstrated. Well-defined QDs and an amphiphilic copolymer were first prepared and the amphiphilic copolymer was then used to disperse the QDs ... |

Triplet exciton dissociation in singlet exciton fission photovoltaics.
Adv. Mater. 24(46) , 6169-74, (2012) Triplet exciton dissociation in singlet exciton fission devices with three classes of acceptors are characterized: fullerenes, perylene diimides, and PbS and PbSe colloidal nanocrystals. Using photocurrent spectroscopy and a magnetic field probe it is found t... |
