Fluorescence efficiency of individual carbon nanotubes (2007)
Carlson, Lisa J., Maccagnano, Sara E., Zheng, Ming, Silcox, John, Krauss, Todd D.
The luminescence efficiency of individual single-walled carbon nanotubes was determined by comparing the fluorescence from individual nanotubes to single CdTe/ZnS quantum dots with a well-defined...
Uncovering forbidden optical transitions in PbSe nanocrystals (2007)
Peterson, Jeffrey J., Huang, Libai, Delerue, Christophe, Allan, Guy, Krauss, Todd D.
The 1S(h,e)-1P(e,h) exciton transition energy of PbSe nanocrystals was determined via two-photon photoluminescence excitation spectroscopy and was found to be in good agreement with predictions from...
Harbold, Jeffrey M., Wise, Frank W., Du, Hui, Krauss, Todd D., Cho, Kyung-Sang, Murray, Chris B.
The relaxation of strongly-confined electrons and holes between 1P and 1S levels in colloidal PbSe nanocrystals has been time-resolved using femtosecond transient absorption spectroscopy. In contrast...
Semiconductor Nanocrystal Photonics (1998)
The overall objective of the project is to take advantage of the unique photon density of states of periodic structures to enhance the energy transfer between two sizes of semiconductor nanocrystals...
The structural basis for giant enhancement enabling single-molecule Raman scattering
Wang, Zhenjia, Pan, Shanlin, Krauss, Todd D., Du, Hui, Rothberg, Lewis J.
We find that giant surface-enhanced Raman scattering for adsorbates on silver surfaces is present only on surfaces that exhibit self-similar fractal topology as inferred from atomic force microscopy....

Ensign, Amy A., Jo, Iris, Yildirim, Ilyas, Krauss, Todd D., Bren, Kara L.
FRET between the zinc porphyrin (ZnP) chromophore in zinc-substituted cytochrome c (Zn-cyt c) and an Alexa Fluor dye attached to specific surface sites was used to characterize Zn-cyt c unfolding....
