Sensitized thulium blue upconversion emission in Nd3+/Tm3+/Yb3+ triply doped lead and cadmium germanate glass excited around 800 nm
(American Institute of Physics (AIP), 2003-11-01)
Bright blue upconversion emission by thulium ions in PbGeO3-PbF2-CdF2 glass triply doped with Nd3+-Tm3+-Yb3+ under diode laser excitation around 800 nm is reported. The results revealed that the Nd3+/Tm3+/Yb3+-codoped ...

Structural characterization on batio3/la2/3ca1/3mno3 bilayers deposited on nb:srtio3
(Universidad Nacional de Colombia, Bogotá, 2014-09-13)
In this work we have investigated structural properties of La2/3Ca1/3MnO3/BaTiO3 bilayers grown on Nb:SrTiO3 substrates. The films were deposited by pulsed laser deposition (PLD) technique at high-pressure oxygen atmosphere ...
Neutrino mixing and the minimal 3-3-1 model
(World Scientific Publ Co Pte Ltd, 2003-08-30)
In the minimal 3-3-1 model charged leptons come in a nondiagonal basis. Moreover, the Yukawa interactions of the model lead to a non-hermitian charged lepton mass matrix. In other words, the minimal 3-3-1 model presents a ...
The influence of the complexing agent on the luminescence of multicolor-emitting Y2O3:Eu3+,Er3+,Yb3+ phosphors obtained by the Pechini's method
(2021-01-01)
In this study, it is reported the enhancement of the downshifting and the upconversion emission of Y2O3:Eu3+,Er3+,Yb3+ phosphor drove by sorbitol instead of the classic ethylene glycol used as polymerizing agent in the ...
Production of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) P(3HB-co-3HV) with a broad range of 3HV content at high yields by Burkholderia sacchari IPT 189
(SPRINGER, 2008)
The biosynthesis of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) from sucrose and propionic acid by Burkholderia sacchari IPT 189 was studied using a two-stage bioreactor process. In the first stage, this bacterium was ...
Practical synthesis of a functionalized 1-oxo-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The synthesis of a functionalized 1-oxo-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid has been performed in 10 steps from the readily available dimedone. Only three purifications by flash chromatography are required ...
