Potential applications of nanoscale polymer LEDS abound, but efficient nanofabrication methods to produce them remain limited. Reporting in the first issue of the Journal of Physics Materials, Thomas ...

Physicists previously believed that no more than a quarter of the energy flowing into an LED could be emitted as light, with the rest radiating as heat, said university physics chairman Valy Vardeny, ...

New research published in EPJ B reveals that the higher-than-expected efficiency of PLEDs can be reached through interactions between triplet excitons, and impurities embedded in their polymer layers.

(Nanowerk News) Ulsan National Institute of Science and Technology (UNIST) researchers report considerable improvement in device performance of polymer-based optoelectronic devices. Published in ...

Many organic polymers emit light when a voltage is applied to them. This effect arises from the ‘conjugated’ structure of these polymers – that is, the alternate single and double bonds that link the ...

Graded electrical junctions created by molecular scale engineering enable record levels of blue light emitting efficiency from polymer to be achieved. Light emitting polymers are an attractive ...
