White emission in polymer light-emitting diodes: color composition by single-layer electroluminescence and external photoluminescence component
(Elsevier BVAmsterdam, 2014-09)
White emitting devices were obtained through a single component system by combining two materials with different emission properties: a greenish electroluminescent polymer, known as poly[(9,9-dioctylfluorenyl-2,7-diyl)-a ...
White light emitting devices by doping polyfluorene with two red emitters
(ElsevierLausanne, 2013-02)
The photo and electroluminescent properties of a single-layer multi-component blend composed of only blue and red emitters were studied. The blue emitter poly(9,9-dihexyl-2,7-fluorene)] (LaPPS10) was used as the matrix, ...

Photo-oxidation of polyphenylenevinylene chains in Langmuir-Blodgett and cast films
(2005-12-01)
Poly(p-phenylene vinylene) (PPV) derivatives are well known for their applications in polymer light emitting diodes (PLEDs). These derivatives are highly susceptible to photooxidation though, which is mainly caused by the ...

Selección de los agentes reductores más eficientes para el tratamiento de aguas residuales industriales en una PTAR de cromado utilizando la metodología ANP y AHP
(Universidad de La SabanaMaestría en Diseño y Gestión de ProcesosFacultad de Ingeniería, 2012-11-13)
Las aguas residuales de las plantas de cromado son uno de los desechos industriales más contaminantes por sus características tóxicas y corrosivas. Para remover el cromo hexavalente primero se reduce, formando hidróxido ...
On the role of the Indian Ocean as a precursor of ENSO
(Universidad Nacional de ColombiaMedellín - Minas - Maestría en Ingeniería - Recursos HidráulicosFacultad de MinasMedellín, ColombiaUniversidad Nacional de Colombia - Sede Medellín, 2022-11-14)
Although the major aspects that give rise to El Niño-Southern Oscillation (ENSO), the dominant mode of climate variability on the interannual time scale, are reasonably well understood, predicting the state of ENSO before ...
