  2. 6. Bilayer Light-Emitting Electrochemical Cells for Signage and Lighting Applications

    Author : E. Mattias Lindh; Ludvig Edman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; Light-emitting electrochemical cell; Signage; Display; Luminescent line art; Inkjet printing; Direct-write printing; fysik; Physics; Electronics; elektronik;

    Abstract : Artificial light surrounds us in a manifold of shapes. It is mainly utilized for illumination, but also for graphical communication of complex and evolving messages and information, among other things. It can be generated in different ways with incandescent lamps and fluorescent tubes constituting two common examples. READ MORE

  4. 7. Synthesis of Conjugated Polymers and Small Molecules for Organic Light-Emitting Devices and Photodetectors

    Author : Petri Henrik Murto; Chalmers tekniska högskola; []

    Abstract : Production cost and environmental impact are the two major concerns that are related to the conventional optoelectronic devices. It is desirable for the modern semiconductors that they are free of toxic/costly metals, they can be processed with low-cost solution-based methods, and their optical, electronic, and mechanical properties can be easily tuned depending on the target application.

  6. 9. Colors of Life and Optoelectronics: Zinc Porphyrins for Light-Emitting Electrochemical Cells and Organic Photodetectors

    Author : Mariza Mone; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; near-infrared; porphyrins; light emitting electrochemical cell; photomultiplication; optoelectronics; aggregation;

    Abstract : The field of organic optoelectronics constitutes an interdisciplinary field that covers chemistry, physics, materials science and biology. The technological promises of the organic materials over their inorganic counterparts include a lower production cost and the feasibility to be processed through solution-based techniques on large-area and/or flexible substrates.
