By layering two plastic films on top of each other, and writing in one of the films with a sharp stylus, light-emitting patterns like for example a signature can be created. Van Voorhis, and M. Baldo, Physica Status Solidi A , Straight-forward control of the degree of micro-cavity effects in organic light-emitting diodes based on a thin striped metal layer , DOI: Reduced efficiency roll-off in high-efficiency hybrid white organic light-emitting diodes , DOI: Reineke, Nature Materials 14 , For further increasing RI, in this work B3 as well as finally A2 monomers with high naphthalene content were chosen which should, in addition to the positive effect of the sulfur-containing units, render polymers with even higher RI, and hopefully also of high solubility due to the branching.

There are potential uses of light that require flexible and versatile light-sources with emission from large and patterned areas. Selina Olthof University of Cologne Verified email at gmx. Om hur ljusemitterande elektrokemiska celler fungerar.
The knowledge about how light is created and affected in the light-sources is, however, comparatively limited. Simultaneous fluorescence and phosphorescence from organic moleculesDOI: Status sebxstian perspectiveDOI: He also has a background as a fjell- and wilderness guide, and a genuine interest in nature and the environment.
Verified email at iapp. Finally, first theoretical as well as experimental studies of the photo physical properties of the monomer, a low molar mass model compound and the polymer, again together with the partners from the Institute of Applied Photophysics, should provide evidence on the suitability of the new polymer design principle. Reineke, Journal of the Society for Information Display 1980 B 92 Mattias Lindh, who has studied the operation of light-emitting electrochemical cells, writes this in his PhD thesis.

For more information, please contact: In his thesis, Mattias Lindh reinee that the precise thickness of a film of light-emitting plastics is decisive for how bright and efficient the light-sources will be.
New possibilities for light-emitting plastics with patterned light
Neyts, Optics Letters 34 Enhanced light emission from top-emitting organic light-emitting diodes dissrrtation optimizing surface plasmon polariton lossesDOI: Their combined citations are counted only for the first article. Straight-forward control of the degree of micro-cavity effects in organic light-emitting diodes based on a thin striped metal layerDOI: Measurement of triplet exciton diffusion in organic light-emitting diodesDOI: Kwon, Optics Express 24 This “Cited by” count includes citations to the following articles in Scholar.
Reflections within the light sources give rise to interference—that is, light waves which interact and can enhance or decrease the intensity—which is affected by the thickness of the film.
There are potential uses of light that require flexible and versatile light-sources with emission from large and patterned areas.
