Momentum-resolved surface enhanced Raman scattering from a nanowire-nanoparticle junction cavity
Adarsh B. Vasista, Shailendra K. Chaubey, David J. Gosztola +3
Herein we report experimental evidence of directional SERS from molecules situated inside a single nanowire-nanoparticle junction cavity. The emission was confined to a narrow rang…
Accelerating ultrafast spectroscopy with compressive sensing
Sushovit Adhikari, Cristian L. Cortes, Xiewen Wen +5
Ultrafast spectroscopy is an important tool for studying photoinduced dynamical processes in atoms, molecules, and nanostructures. Typically, the time to perform these experiments…
Life-time and line-width of individual quantum dots interfaced with graphene
Xin Miao, David J. Gosztola, Anirudha V. Sumant +1
We report on the luminescence's life-time and line-width from an array of individual quantum dots; these were interfaced with graphene surface guides or dispersed on a metal film.…
Confinement Effect Emission from Infiltrated ZnO in PS-b-PMMA Nanostructures
Paris L. Blaisdell-Pijuan, David J. Gosztola, Angel Yanguas-Gil +5
We have characterized the growth of ZnO using sequential infiltration synthesis (SiS) on PS-b-PMMA block copolymers (BCP) of spherical and cylindrical sub-20nm morphologies and stu…
Femtosecond electron and x-ray source based on laser wakefield accelerator
Dmitri A. Oulianov, Yuelin Li, Robert A. Crowell +4
A terawatt tabletop laser wakefield acceleration source of relativistic electrons has been developed in our Terawatt Ultrafast High Field Facility (TUHFF). The preliminary results…
Recombination of Geminate (OH,eaq-) Pairs in Concentrated Alkaline Solutions: Lack of Evidence For Hydroxyl Radical Deprotonation
Rui Lian, Robert A. Crowell, Ilya A. Shkrob +3
Picosecond dynamics of hydrated electrons and hydroxyl radicals generated in 200 nm photodissociation of aqueous hydroxide and 400 nm (3-photon) ionization of water in concentrated…
