          Abstract

          Organic semiconductors are a new class of materials representing an innovative field of scientific research. Efficient illuminants, such as organic light emitting diodes (OLEDs), will soon help reduce the world's energy consumption for lightning. Today OLEDs can already be found in ultra-thin and super-bright displays of modern mobile high-tech applications. This contribution provides an experimental and conceptual approach for the curricular integration of luminescent semiconducting polymers into science classes.

          Los semiconductores orgánicos son una nueva clase de materiales que representan un campo novedoso de investigación científica. Proveen de luz eficientemente, tales como los diodos emisores de luz orgánicos (OLED, por sus siglas en inglés) pronto serán útiles para reducir el consumo mundial de luz. Hoy los OLEDs pueden encontrarse en las carátulas de dispositivos modernos ultra-delgados y súper-brillantes con aplicaciones de alta tecnología móvil. Esta contribución da un enfoque experimental y conceptual para integrar en el currículo escolar los polímeros luminiscentes semiconductores.

              Simple assembling of organic light-emitting diodes for teaching purposes in undergraduate labs

              Electroluminescent organic molecules and polymers have emerged as advanced materials used to fabricate organic light-emitting diodes (OLEDs) whose unique technological features could revolutionize the industry of flat-panel displays. Although in many cases these novel organic materials combine low cost and ease of processing, OLEDs fabrication for educational purposes has rarely been reported. In this work, we report a simple and inexpensive method to fabricate organic electroluminescent devices intended for educational purposes at the undergraduate level of physics, chemistry and material sciences. For ease of fabrication the cathode in the diode structure was formed by either an alloy of Bi-Pb-Cd-Sn or by a Ga-In alloy in the liquid phase, or simply by silver paint, whereas we used ITO (Indium Tin Oxide) deposited on glass substrates as the anode. Substrates of flexible plastic were also used. The OLEDs were fabricated using the spin-coating technique with solutions of the fluorescent materials Alq3 and MEH:PPV, as well as the phosphor complex Ru(bpy)3. We report measurement data on current-voltage curves, luminescence, and efficiencies obtained by students fabricating and testing the devices under normal room conditions
