ABSTRACT
The world of organic light-emitting diodes (OLEDs) represents one of the most interesting areas of scientific research in the field of optoelectronic devices. The strong efforts made in recent years and the current OLEDs scientific state of the art have led to a fast transition from the academic research to the market, although there are still some problems to overcome, such as the low life span of these products compared with the traditional ones. Meanwhile, the scientific community still considers that the organic electroluminescent materials and devices will be the next generation of light emitters. The applications include all of the known products in the market, ranging from displays to general solid-state lighting, passing to the artistic and architectural environment utilization. Such wide-span use is only possible due the exceptional specifications of the organic electroluminescence materials that allow us to have a really thin (nanometer-scale) emitter, suitable for incorporation virtually anywhere. Additionally, nowadays new organic materials are presently being synthesized, opening even further possibilities for the field.
