Results in brief
White Light Emitting Lanthanide Metal Complexes for Electroluminescent Materials
The need to reduce energy consumption has prompted a considerable research effort for developing new energy-efficient lighting systems to replace conventional light sources (i.e. incandescent and fluorescent lamps). At present, both inorganic, i.e. based on silicon semiconductor technology, or organic light emitting diodes (OLEDs), stand out as the best alternative lighting devices, in term of efficiency and duration. White light production for general lighting applications requires the generation and the intensity control of the three fundamental (red, green and blue) or two complementary (blue and yellow) colors. Desirable properties for a candidate emitting material are high luminescence intensity, color purity, easy synthesis, good chemical and electrical stability, and low cost production. The wider availability of white emitting materials will foster their utilization in the next generation of lighting solution, reinforcing the traditional leadership of the European industries in the field. Addressing and providing innovative solutions to the important scientific challenges surrounding the materials for lighting solutions is expected to impact on the everyday quality of life in the EU and beyond. The main scientific objective of this project is the development of white light emissive materials that are highly efficient, thermally, photo- and electrochemically stable and possess electron and hole transport character. These properties make them suitable for the development of white OLEDs (WOLEDs), or other electroluminescent devices, such as Light Electrochemical Cells (LECs).

Project objective
There is an urgent need to develop a new generation of more efficient and durable illumination sources to surpass thelimitations of the conventional lighting systems. Solid State Lighting sources based on Light Emitting Diodes (LEDs) orOrganic LEDs (OLEDs) devices are emerging as the next generation systems for general illumination. White LEDs on themarket outperform the traditional incandescent and fluorescent lamps, both in term of efficiency and lifetime. More work hasstill to be done to develop their organic counterpart, OLEDs. These offer the distinctive possibility to fabricate large area flatand also flexible devices by vacuum or solution processing, i.e. by potentially less expensive and less energy-consumingproduction protocols. For this, the development of electroluminescent materials that show high brightness, easy synthesis,good chemical and electrical stability, low cost, and simple processing is actively pursued. In this context, WHITELIGHTtargets the development of single-molecule white light emitting materials for the fabrication of OLEDs, containing Eu(III)(red), Tb(III) (green) lanthanide ions and bis(2-pyridyl)amine based ligands (blue) emitters. This is a very ambitious andmultidisciplinary goal that requires a range of expertise spanning from theoretical chemistry to physical device fabricationand testing. The research unit at the hosting institution has a strong background in the photophysics of materials for light/energy conversion, complemented by an expertise in the design and synthesis of organic luminescent materials, as well asthe fabrication and testing of electroluminescent devices. On the other hand, the Experienced Researcher has a strongbackground in the synthesis of luminescent lanthanide complexes. This unique combination of expertise is a major factor forthe successful implementation of the proposed research.
