Bright Fluorophores in the Second Near-Infrared Window: HgSe/CdSe Quantum Dots
Ananth Kamath, Richard D. Schaller, Philippe Guyot-Sionnest
Fluorophores emitting in the NIR-IIb wavelength range (1.5 micron - 1.7 micron) show great potential for bioimaging due to their large tissue penetration. However, current fluoroph…
Extrinsic Voltage Control of Carrier Lifetime in Polycrystalline PbSe Mid-wave IR Photo Detectors for Increased Detectivity
Samiran Ganguly, Tang Xin, Sung-Shik Yoo +2
Polycrystalline PbSe for mid-wave IR (MWIR) photodetector is an attractive material option due to high operating/ambient temperature operation and relatively easy and cheap fabrica…
Transport properties of mid-infrared colloidal quantum dot films
Emmanuel Lhuillier, Sean Keuleyan, Philippe Guyot-Sionnest
The transport and thermal properties of HgTe colloidal quantum dot films with cut-off wavelengths in the mid-IR are investigated. The cut-off wavelength of this material can be tun…
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 ~…
