Fast non-radiative decay in o-aminophenol
(American Chemical Society, 2014-01)
The gas phase structure of 2-aminophenol has been investigated using UV-UV as well as IR-UV hole-burning spectroscopy. The presence of a free OH vibration in the IR spectrum rules out the contribution of the cisisomer, ...
Fast Nonradiative Decay ino‑Aminophenol
(American Chemical Society, 2014-02)
The gas phase structure of 2-aminophenol has been investigated using UV–UV as well as IR–UV hole burning spectroscopy. The presence of a free OH vibration in the IR spectrum rules out the contribution of the cis isomer, ...
Photochemistry and Photophysics of Shinorine Dimethyl Ester
(Wiley Blackwell Publishing, Inc, 2018-09)
The photostability and photophysical properties of the dimethyl ester of the mycosporine-like amino acid shinorine have been experimentally evaluated in aqueous solution and in the presence of direct micelles prepared with ...
Fluorescence Quantum Yields in Complex Environments from QM-MM TDDFT Simulations: The Case of Indole in Different Solvents
(American Chemical Society, 2020-11)
Fluorescence is commonly exploited to probe microscopic properties. An important example is tryptophan in protein environments, where variations in fluorescence quantum yield, and in absorption and emission maxima, are ...
The role of quantum confinement and crystalline structure on excitonic lifetimes in silicon nanoclusters
(American Institute of Physics, 2010-07)
The emission energy dependence of the photoluminescence (PL) decay rate at room temperature has been studied in Si nanoclusters (Si-ncl) embedded in Si oxide matrices obtained by thermal annealing of substoichiometric Si ...
Effect of Ag+ on the Excited-State Properties of a Gas-Phase (Cytosine)2Ag+ Complex: Electronic Transition and Estimated Lifetime
(American Chemical Society, 2014-06)
Recently, DNA molecules have received great attention because of their potential applications in material science. One interesting example is the production of highly fluorescent and tunable DNA–Agn clusters with cytosine ...
Trapping of Rhodamine 6G excitation energy on cellulose microparticles

Trapping of R6G excitation energy on cellulose microparticles
(Royal Society of Chemistry, 2010)
The binuclear dual emitter [Br(CO)3Re(P⋯N)(N⋯P)Re(CO)3Br] (P⋯N): 3-chloro-6-(4-diphenylphosphinyl)butoxypyridazine, a new bridging P,N-bidentate ligand resulting from the ring opening of tetrahydrofuran
(Royal Society of Chemistry, 2017-01)
Lithium diphenylphosphide unexpectedly provokes the ring-opening of tetrahydrofuran (THF) and by reaction with 3,6-dichloropyridazine leads to the formation of the ligand 3-chloro-6-(4-diphenylphosphinyl)butoxypyridazine ...
Electroluminescence transients and correlation with steady-state solar output in solution-prepared CH3NH3PbI3 perovskite solar cells using different contact materials
(IOP Publishing, 2020-01)
Electroluminescence (EL) transients of solution-prepared CH3NH3PbI3 perovskite solar cells were recorded under different biasing voltage conditions. The EL transients are reversible and show a sharp increase and a peak in ...
