Photoexcitation of a volume plasmon in C60 ions.
S W J Scully,Erik D. Emmons,M. F. Gharaibeh,R. A. Phaneuf,A. L. D. Kilcoyne,Alfred S. Schlachter,Stefan Schippers,A. Müller,Himadri Chakraborty,Mohamed Madjet,Jan-Michael Rost +10 more
TL;DR: Time-dependent density functional calculations confirm the collective nature of this feature, which is characterized as a dipole-excited volume plasmon made possible by the special fullerene geometry.
Journal Article
Photoexcitation of a Volume Plasmon in C$_{60}$ Ions
R. A. Phaneuf,Erik D. Emmons,M. F. Gharaibeh,A. L. D. Kilcoyne,Alfred S. Schlachter,Stefan Schippers,Allison Mueller,Himadri Chakraborty,Mohamed Madjet,Jan-Michael Rost,S W J Scully +10 more
TL;DR: In this article, a dipole-excited volume plasmon made possible by the special fullerene geometry is characterized as dipole excitation in the photon absorption spectrum of neutral C60.
Journal ArticleDOI
Semi-Automated Detection of Trace Explosives in Fingerprints on Strongly Interfering Surfaces with Raman Chemical Imaging:
Ashish Tripathi,Erik D. Emmons,Phillip G. Wilcox,Jason A. Guicheteau,Darren K. Emge,Steven D. Christesen,Augustus W. Fountain +6 more
TL;DR: The ability to nondestructively identify explosives on fingerprints present on commonly found surfaces such that the fingerprint remains intact for further biometric analysis is demonstrated.
Journal ArticleDOI
Raman chemical imaging of explosive-contaminated fingerprints.
Erik D. Emmons,Ashish Tripathi,Jason A. Guicheteau,Steven D. Christesen,Augustus W. Fountain +4 more
TL;DR: The ability to identify explosives nondestructively so that the fingerprint remains intact for further biometric analysis is shown.
Journal ArticleDOI
Kinetics and Reaction Mechanisms of Thiophenol Adsorption on Gold Studied by Surface-Enhanced Raman Spectroscopy
Ashish Tripathi,Erik D. Emmons,Steven D. Christesen,Augustus W. Fountain,Jason A. Guicheteau +4 more
TL;DR: In this paper, the authors performed time-, temperature-, and pH-dependent measurements of thiophenol adsorption on commercial nanostructured gold SERS substrates, and observed both physisorption and chemisorsorption processes.
