Fluorescence quantum yield of Yb3+-doped tellurite glasses determined by thermal lens spectroscopy
(Elsevier B.V., 2017-01-01)
In this work, the combination of three different thermal lens spectroscopic methodologies was used to better determine the fluorescence quantum yield and to observe the concentration quenching in Yb3+-doped binary tellurite ...
Time fluctuations in isolated quantum systems of interacting particles
(American Physical Society, 2013-09)
Numerically, we study the time fluctuations of few-body observables after relaxation in isolated dynamical quantum systems of interacting particles. Our results suggest that they decay exponentially with system size in ...
Interaction between nitroxyl radicals and CdTe quantum dots: Determination of fluorescence-quenching mechanisms in aqueous solution
(2019)
The present work characterizes the optical properties of CdTe quantum dots (CdTe QDs) after interaction with nitroxyl radicals based on steady-state and time-resolved fluorescence spectroscopy studies. QDs of different ...
Absolute thermal lens method to determine fluorescence quantum efficiency and concentration quenching of solids

QUENCHING OF TRIPLET BENZOPHENONE BY VITAMINS E and C and BY SULFUR CONTAINING AMINO ACIDS and PEPTIDES
(1985)
Abstract— The quenching rate of triplet benzophenone in water and/or water mixtures has been determined employing vitamin C, vitamin E, cystine, cysteine, reduced and oxidized glutathione, methionine and DL‐penicillamine. ...
Quantum coherence and criticality in irreversible work
(American Physical Society, 2020-08)
The irreversible work during a driving protocol constitutes one of the most widely studied measures in nonequilibrium thermodynamics, as it constitutes a proxy for entropy production. In quantum systems, it has been shown ...
Dynamical quenching of tunneling in molecular magnets
(2015)
It is shown that a single molecular magnet placed in a rapidly oscillating magnetic field displays the phenomenon of quenching of tunneling processes. The results open a way to manipulate the quantum states of molecular ...
Fluorescence of polyaniline films on electrode surfaces: Thickness dependence and surface influence
(Elsevier Science Sa, 2009-07)
The dependence of the photoluminescence of polyaniline films, supported onto platinum or fluorine-doped SnO2 (FTO) electrodes, on the film thickness (as measured by the voltammetric charge) has been studied for different ...
