  1. 1. 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

  2. 2. 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.

  3. 3. Conjugated polymers for optoelectronics

    University dissertation from Chalmers University of Technology

    Author : Lars Lindgren; Chalmers tekniska högskola.; Chalmers University of Technology.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymerkemi; Polymer chemistry; Conjugated polymers; Polyfluorenes; Polymer Solar Cells; Polymer Light-Emitting Diodes;

    Abstract : The work presented in thesis is divided into two parts; conjugated polymers for light-emitting diodes and conjugated polymers for solar cells. The main focus was on the synthesis and characterisation of the conjugated polymers, together with device preparation and characterisation. READ MORE

  4. 4. 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.

  5. 5. Electronic characterization of molecules with application to organic light emitting diodes

    University dissertation from Stockholm : KTH

    Author : Emil Jansson; KTH.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; OLED; DFT; Marcus theory; Response theory; NATURAL SCIENCES Chemistry Theoretical chemistry; NATURVETENSKAP Kemi Teoretisk kemi;

    Abstract : The presented thesis is devoted to the field of organic light emittingdiodes (OLEDs). Time-dependent Kohn-Sham density functional theory(TDDFT) is applied in order to eludicate optical properties such as fluorescence andphosphorescence for some of the most important materials.
