Blue, Green and Orange-Red Light Emitting Polymers: Synthesis, Characterization and Prospects of Applications in Optoelectronic Devices

Light emitting polymers (LEPs) are considered as the second generation of conducting polymers. A Prototype LEP device based on electroluminescence emission of poly(p-phenylenevinylene) (PPV) was first assembled in 1990. LEPs have progressed tremendously over the past 20 years. The development of new LEP derivatives are important because polymer light emitting diodes (PLEDs) can be used for the manufacture of next-generation displays and other optoelectronic applications such as lasers, photovoltaic cells and sensors. Under this circumstance, it is important to understand thermal, structural, morphological, electrochemical and photophysical characteristics of luminescent polymers. In this thesis the author synthesizes a series of light emitting polymers that can emit three primary colors (RGB) with high efficiency

Comunicación personalizada : iniciativas de la Fundación Orange en comunicación aumentativa y tecnología.

Se presentan algunos de los proyectos promovidos por la Fundación Orange que pretenden mejorar la calidad de vida de personas discapacitadas a través de sistemas de comunicación alternativos basados en las nuevas tecnologías. Los trabajos se dividen en dos apartados: tecnologías visuales para personas con autismo y el proyecto In-TIC, aplicación que permite la accesibilidad y usabilidad de las TIC por parte de distintos colectivos de discapacitados..
