Decay time characteristics of La2O2S:Eu and La2O2S:Tb for use within an optical sensor for human skin temperature measurement [PDF]

, 2008
We focus on the development of a remote temperature sensing technology, i.e., an optical laser-based sensor, using thermographic phosphors for medical applications, particularly within an electromagnetically hostile magnetic resonance imaging (MRI ...

Photochemistry and Photophysics of Coordination Compounds of the Main Group Metals [PDF]

, 1992
The photoproperties of main group metal complexes with the electron configurations s2 (e.g. T l + , Sb3 + , Te4 + ) and s° (e.g. T l 3 + , Pb4 + ) were studied on the basis of a general concept which relates characteristic excited states to typical ...

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.

Exciton coupling in molecular crystals [PDF]

The implications of perfect exciton coupling and molecular vibrations were investigated, as well as the effect they have on the lifetime of singlet and triplet excitons coupled in a limiting geometry. Crystalline bibenzyl, Cl4Hl4, provided a situation in

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 ...
