We present a theoretical and experimental study of a multilayer organic light emitting device (OLED) with a partially doped emission layer. An extended version of our established "MOLED" device model is used to understand the effects of the partially doped ...
This work deals with the engineering of a new luminescent complex of lanthanide, able to be specifically grafted onto biological materials and to emit a characteristic light useful in quantifying the concentration of the target molecules. We have based our ...
Doping of organic light-emitting devices using highly luminescent molecules is a well-established strategy to improve brightness, efficiency and lifetime or to adjust emission color and color purity. Laser dyes from the pyran-containing donor-acceptor fami ...
Biogas as renewable source of energy is underexploited. We extrapolate the potential recoverable from waste streams in the EU-15 to 769 PJ (17.5 Mtoe), of which under 10% is used (1.7 Mtoe). SOFC can promote the valorisation of biogas in small CHP installa ...
We report on the enhancement of the photoluminescence (PL) intensity from a nanostructured organic material composed of nanosized aggregates of poly(para-phenylene) (PPP) in a polystyrene insulating matrix. In addition, the peak of the PL emission spectrum ...
The hydrogenase maturation proteins HypF and HypE catalyze the synthesis of the CN ligands of the active site iron of the NiFe-hydrogenases using carbamoylphosphate as a substrate. HypE protein from Escherichia coli was purified from a transformant overexp ...
Wide quantum wells, where the energy spacing between the first two energy levels is lower than the energy of the polar optical phonon, could represent the ideal condition to obtain a population inversion and the production of infrared lasers. On the other ...
Highly structured fluorescence and fluorescence excitation spectra of C70 in Ne matrixes are reported. Fluorescence from both S1 and S2 states is obsd., and these are identified as being of A2' and E1' and have energies of 15,524 cm-1 and 15,691 cm-1, resp ...
Four new Ru polypyridyl complexes with mono- or di((2-thienyl)ethenyl) substituted bipyridines were synthesized. The complexes were characterized by NMR, elemental anal., UV-visible absorption and electrochem. (differential pulse and cyclic voltammetry). E ...
The ion-pair state emission spectra of I2 isolated in Ne, Ar, and Kr matrixes at 300-700 nm and vacuum UV spectra at 50,000-60,000 cm-1 are presented. Spectroscopic anal. of the UV and visible emission bands of the lowest-lying ion-pair state D'(2g) in Ne ...
