Exciton and Hole-Transfer Dynamics in Polymer: Fullerene Blends

Autor: Serbenta, A., Pavelyev, V.G., Hummelen, J.C., Loosdrecht, P.H.M. van, Pshenichnikov, M.S., Chergui, Majed, Cundiff, Steve, Taylor, Antoinette, Vivie-Riedle, Regina de, Yamanouchi, Kaoru

Ultrafast hole transfer dynamics from fullerene derivative to polymer in bulk heterojunction blends are studied with visible-pump – IR-probe spectroscopy. The hole transfer process is found to occur in 50/300 fs next to the interface, while a longe

Ultrafast Pump-Push Photocurrent Spectroscopy of Organic Photoconversion Systems

Autor: Bakulin, A.A., Rao, A., Vaynzof, Y., Gelinas, S., Pavelyev, V.G., Loosdrecht, P.H.M. van, Pshenichnikov, M.S., Niedzialek, D., Cornil, J., Beljonne, D., Friend, R.H., Chergui, Majed, Cundiff, Steve, Taylor, Antoinette, Vivie-Riedle, Regina de, Yamanouchi, Kaoru

Publikováno v: Proceedings of the XVIIIth International Conference on Ultrafast Phenomena, 41(41)

Novel optical pump-push – photocurrent probe ultrafast spectroscopy experiments on organic photoconversion systems show that excessive excitation energy in such systems is not lost but used to reach delocalised states that act as the gateway for lo

Probing the origin of fluorescence quenching of a graphene-porphyrin hybrid material

Autor: Sharma, Divya, Zhang, Xiaoyan, Browne, Wesley R., Herek, Jennifer L., Huijser, Annemarie, Feringa, Bernard, Chergui, Majed, Cundiff, Steve, Taylor, Antoinette, Vivie-Riedle, Regina de, Yamanouchi, Kaoru

Publikováno v: Proceedings of the XVIIIth International Conference on Ultrafast Phenomena, 41(41)

We report transient absorption spectroscopic studies on the hybrid material composed of porphyrin molecules covalently attached to graphene for investigating the mechanism underlying the reported fluorescence quenching of porphyrin in the hybrid. Exc

Acceptor Energy Offset Manages Ultrafast Recombination Dynamics in Donor-Acceptor Mixtures

We study charge recombination rates in blends of MEH-PPV and a comprehensive set of low molecular-weight fluorine-based acceptors, using visible-pump – IR-probe photoinduced absorption technique. The positions of acceptor’s HOMO-LUMO levels are e

Ultrafast ignition of a uni-directional molecular motor

Autor: Conyard, Jamie, Addison, Kiri, Heisler, Ismael A., Cnossen, Arjen, Browne, Wesley R., Meech, Stephen R., Feringa, Bernard, Chergui, Majed, Cundiff, Steve, Taylor, Antoinette, Vivie-Riedle, Regina de, Yamanouchi, Kaoru

Publikováno v: Proceedings of the XVIIIth International Conference on Ultrafast Phenomena, 41(41)

Light-driven molecular motors convert light into mechanical energy via excited state reactions. In this work we follow sub-picosecond primary events in the cycle of a two-stroke unidirectional motor by fluorescence up-conversion and transient absorpt

We present two milestone results that confirm that thin disk lasers are excellent candidates for driving extreme nonlinear optics experiments. In a first experiment using the broadband mixed sesquioxide gain material Yb:LuScO3, we demonstrate that th

Time resolved optical reflectivity and x-ray diffraction techniques are employed to study the laser-induced structural response in two charge and orbitally ordered manganites. Optical data indicate a non-thermal nature of the laser-triggered phase tr

We examine the optical response of a virtual dipole transition of a quantum mechanical two-level system (TLS). In the case of off-resonant excitation the time-integrated dipole response (TIDR) is expected to be zero, which corresponds to transparency
