Light Emitting Materials for Organic Electronics

Device Structures and Materials for Organic Light Emitting Diodes

Organic light emitting devices (OLEDs) are promising candidates for light-weight color flat panel displays. Different device structures with emission in the blue, green, and red spectral region are discussed with respect to their optical and electrical characteristics. Blue OLEDs based on OXD-8 as emitter molecule show quantum efficiencies of 0.9 % (2.2 cd/A, 0.6 lm/W), green emitting devices b...

Phosphorescent materials for application to organic light emitting devices*

Organic phosphors have demanded the attention of the organic electroluminescence community because they enable ef®ciencies quadruple that of ̄uorescent materials. In this work, we review the categories of organic phosphors: lanthanide complexes, organic phosphors and metal-organic complexes. The characteristics necessary for ef®cient phosphorescence are considered and conclusions are drawn as t...

Organic light-emitting transistor technology

The organic light-emitting transistor (OLET) is an emerging optoelectronic device having the structure of a thin-film transistor and the capability of light generation [1]. Bright/multicolor OLETs may allow electroluminescent display fabrication with simpler driving circuits. Furthermore, the most advanced OLETs encompass a huge technological potential for the realization of intense nanoscale l...

simulations for organic light - emitting diodes

The physical and chemical properties of tris(8-hydroxyquinolinato)aluminum (Alq3), one of the organic materials most commonly used as the light-emitting layer of OLEDs, and the interface with possible metal cathodes are investigated by means of first-principles computer simulations. A number of new insights have emerged from this study, and we emphasize the consequences of the properties thus d...
