On/Off Fluorescence Intermittency of Single Semiconductor Quantum Dots

July 1, 2001
Author(s)
M Kuno, D P. Fromm, H F. Hamann, Alan Gallagher, David Nesbitt
Single molecule confocal microscopy is used to investigate the detailed kinetics of fluoresence intermittency in colloidal H-VI (CdSe) semiconductor quantum dots. two distinct modes of behavior are observed corresponding to i) sustained on episodes (Τ on)

On/Off Flurescence Intermittency of Single Semiconductor Quantum Dots

July 1, 2001
Author(s)
M Kuno, D P. Fromm, H F. Hamann, Alan Gallagher, David Nesbitt
Single molecule confocal microscopy is used to investigate the detailed kinetics of fluorescence intermittency in colloidal II-VI (CdSe) semiconductor quantum dots. Two distinct modes of behavior are observed corresponding to (i) sustained on episodes (τ

Fast Vibrational Relaxation of OH (N=9) by Ammonia and Ozone

June 1, 2001
Author(s)
S A. Nizkorodov, W W. Harper, David Nesbitt
Vibrational removal of OH(X 2II) out of v=9 by 0 3 and NH 3 has been studied in a flow cell flash-photolysis apparatus using high-resolutiondirect infrared absorption detection of OH in the v=11

Fast Vibrational Relaxation of OH (v=9) By Ammonia and Ozone

June 1, 2001
Author(s)
S A. Nizkorodov, W W. Harper, David Nesbitt
Vibrational relaxation of OH(X 2II) in the Ņ=9 state by O 3 and NH 3 has been studied via flash-photolysis using high-resolution direct infrared absorption detection of OH in the Ņ= 11

May 1, 2001
Author(s)
D Z. Anderson, J E. Faller, M J. Holland, L Kolvalenko, S R. Leone, R McCray, David Nesbitt
The revised JILA brochure, written for those interested in NIST programs as well as for prospective graduate students, postdoctoral associates, and visiting fellows, provides an overview of JILA and its mission, and explains the joint nature of the

Molecular Fluorescence in the Vicinity of a Nanoscopic Probe

May 1, 2001
Author(s)
H F. Hamann, M Kuno, Alan Gallagher, David Nesbitt
The dramatic modifications of molecular fluorescence in the proximity of a sharp nanoscopic probe is investigated by an apertureless or antenna-based near-field scanning optical microscope, which exploits the interactions between a fluorescent sample and a
