  1. 1. Polymer light-emitting electrochemical cells Utilizing doping for generation of light

    University dissertation from Umeå : Department of Physics, Umeå University

    Author : Piotr Matyba; Umeå universitet.; [2011]
    Keywords : ;

    Abstract :     The current implementation of conjugated polymers (“conducting plastics”) in a wide range of devices promises to bring the vision of a new generation of flexible, efficient and low-cost applications to reality. Plastic lightemitting devices in the form of polymer light-emitting diodes (PLEDs) are projected to be particularly close to the market in applications such as large area and conformable illumination panels and high-performance thin displays.

  2. 2. Light-Emitting Electrochemical Transistors

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Jiang Liu; Linköpings universitet.; Linköpings universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Since the discovery of conductive polymers in 1977, the implementation of organic conjugated materials in electronic applications has been of great interest in both industry and academia. The goal of organic electronics is to realize large-area, inexpensive and mechanically-flexible electronic applications. READ MORE

  3. 3. Inorganic-Organic Hybrid Technology for Light Emitting Diodes

    University dissertation from Liu Tryck : Linköping University Electronic Press

    Author : Amal Wadeasa; Linköpings universitet.; Linköpings universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Since the first report of inorganic light emtting diodes a century ago the field of inorganic light emitting diodes has evolved rapidly. T he development of light emitting diodes technology has caused their efficiency and light output to increase exponentially, with a doubling occuring about every 36 months  since the 1960s, in a similar way to Moor´s law.

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

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Petri Henrik Murto; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solution processing; conjugated polymers; fluorescence; near-infrared; light-emitting electrochemical cell; organic photodetector; organic light-emitting diode;

    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.
