Fluorescence and phosphorescence from individual C$_{60}$ molecules excited by local electron tunneling

, 2005
Using the highly localized current of electrons tunneling through a double barrier Scanning Tunneling Microscope (STM) junction, we excite luminescence from a selected C$_{60}$ molecule in the surface layer of fullerene nanocrystals grown on an ultrathin

Room temperature triplet state spectroscopy of organic semiconductors [PDF]

, 2013
Organic light-emitting devices and solar cells are devices that create, manipulate, and convert excited states in organic semiconductors. It is crucial to characterize these excited states, or excitons, to optimize device performance in applications like

Photoluminescence, recombination induced luminescence and electroluminescence in epoxy resin [PDF]

, 2001
Dielectric breakdown of epoxies is preceded by light emission, or so-called electroluminescence, from the solid-state material. Very little is known about the luminescence properties of epoxies.

Energy Threshold for D+H_2→DH+H Reaction [PDF]

, 1966
We have been able to measure the threshold energy Eo for the reaction D+H_2→DH+H. The value obtained was (0.33±0.02) eV. Apparently, this is the first direct determination of a threshold energy for a reaction involving the ...
