  1. 1. Chemical and electronic structure of electroluminescent materials and interfaces in polymer-LEDs

    Author : Annica Andersson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conjugated polymer; XPS; UPS; LED; ITO; interface; chemical interaction; doping;

    Abstract : Following the discovery that conjugated polymers can be used as the emitting layer in light­ emitting devices, extensive studies on these materials have been carried out. In a few years, due to the development of new materials and an increasing knowledge of the underlying chemistry and physics, the performance has improved a lot. READ MORE

  2. 2. Light polarization in single molecule spectroscopy: From visualization of structural anisotropy and energy transfer to super-resolution imaging with orientational contrast

    Author : Daniel Thomsson; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Single-molecule spectroscopy; π-conjugated polymers; blinking; fluorescence brightness; low temperature; polarization anisotropy; 2D polarization; energy transfer; super resolution; Fourier transform;

    Abstract : Π-conjugated polymers are an important class of materials which can be used in e.g. photoelectric (solar cells) or electroluminescent (displays) devices. These materials are implemented in a number of applications these days since a lot is already known about them. READ MORE

  3. 3. Conjugated Luminescent Molecular Materials : An Experimental and Theoretical Study of Electronic, Optical and Chemical Properties of some Conjugated Molecules, Polymers and Interfaces

    Author : Nicklas Johansson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In recent years intensive studies of conjugated polymers and molecules have been carried out all over the world. The most promising use for these materials appears at the moment to be as the active luminescent component in flat panel displays. READ MORE

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

    Author : E. Mattias Lindh; Ludvig Edman; Umeå universitet; []

    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
