Photothermal measurement of absorption and scattering losses in thin films excited by surface plasmons
(Optical Society of America, 2009-12)
We present a novel noncontact, photothermal technique, based on the focus error signal of a commercial CD pickup head that allows direct determination of absorption in thin films. Combined with extinction methods, this ...
An experimental and TD-DFT theoretical study on the photophysical properties of Methylene Violet Bernthsen
(Elsevier, 2014-07)
We revisited the photophysics the Methylene Violet (MV) Bernthsen dye in aprotic solvents to rationalize both its peculiar solvatochromism, which cannot be explained by the standard solvatochromic empirical models, and the ...
2-Aminopurine non-radiative decay and emission in aqueous solution: A theoretical study
(ELSEVIER SCIENCE BVAMSTERDAM, 2008)
The minimum energy path along the lowest-lying pi pi* excited state of 2-aminopurine was calculated to elucidate the mechanisms of radiationless decay and emission in water. The sequential Monte Carlo quantum mechanics ...
Optical and physical properties of Er3+-doped oxy-fluoride tellurite glasses
(Elsevier Science BvAmsterdamHolanda, 2011)
Theoretical study of the absorption and nonradiative deactivation of 1-nitronaphthalene in the low-lying singlet and triplet excited states including methanol and ethanol solvent effects
(AMER INST PHYSICSMELVILLE, 2012)
The photophysics of the 1-nitronaphthalene molecular system, after the absorption transition to the first singlet excited state, is theoretically studied for investigating the ultrafast multiplicity change to the triplet ...
Tm and Tm-Tb-doped germanate glasses for S-band amplifiers
(Elsevier B.V., 2008-01-01)
The mechanism involved in the Tm(3+)((3)F(4)) -> Tb(3+)((7)F(0,1,2)) energy transfer as a function of the Tb concentration was investigated in Tm:Tb-doped germanate (GLKZ) glass. The experimental transfer rate was determined ...
On observation of the downconversion mechanism in Er3+/Yb3+ co-doped tellurite glass using thermal and optical parameters
(Elsevier BVAmsterdam, 2015-01)
In this work we report the observed downconversion (DC) mechanism in Er3+/Yb3+-codoped tellurite glasses (in mol%, 80TeO2-10Li2O-10TiO2). The samples were synthesized by the conventional melt-quenching method and then ...
High Nd3+→Yb3+ energy transfer efficiency in tungsten-tellurite glass: A promising converter for solar cells
(2017-05-01)
This work reports on the energy transfer efficiency for Nd3+/Yb3+ co-doped tellurite glasses (80TO2-20WO3, in mol%,). The correlation between Yb3+ ion concentration and the downconversion mechanism was investigated using ...
