Ultrafast resonant optical scattering from single gold nanorods: Large nonlinearities and plasmon saturation
Matthew Pelton, Mingzhao Liu, Sungnam Park +2
We measure nonlinear optical scattering from individual Au nanorods excited by ultrafast laser pulses on resonance with their longitudinal plasmon mode. Isolating single rods remov…

Characterizing Quantum-Dot Blinking Using Noise Power Spectra
Matthew Pelton, David Grier, Philippe Guyot-Sionnest
Fluctuations in the fluorescence from macroscopic ensembles of colloidal semiconductor quantum dots have the spectral form of 1/f noise. The measured power spectral density reflect…

Variable range hopping conduction in semiconductor nanocrystal solids
Dong Yu, Congjun Wang, Brian L. Wehrenberg +1
The temperature and electrical field dependent conductivity of n-type CdSe nanocrystal thin films is investigated. In the low electrical field regime, the conductivity follows G ~…
