Acronym:  LEPDICT

Project code:  PN-III-P2-2.1-PED-2019-3993

Project no: 485PED/2020

Contracting Authority: UEFISCDI - Executive Agency for Higher Education, Research, Development and Innovation Funding

Contractor: ICMPP - "Petru Poni" Institute of Macromolecular Chemistry, Iasi

Duration: 24 months

Budget: 599 986 lei

LEPDICT addressed the topic of light-emitting diodes (LED), one of Europe s Key Enabling Technologies of the 21st Century, and combined efforts and knowledge from organic and polymer chemistry, materials science, physics, and engineering to develop and validate new approaches, and to generate new, basic and applied, transferable knowledge to further push the knowledge in this contemporary research topics.

LEPDICT's goal was to find the optimal combination of active structural elements in the same macromolecular architecture to develop materials capable of acting as active layers in LEDs with minimal efficiency. The main chemical concept used was the construction of luminescent polymer systems containing different emissive species.

Several series of materials (organic compounds, polymers, mixtures, and hybrid materials) with a specific optical response (light emission of a certain color) have been designed, tested, and validated in blue and white light emitting (lab scale) PLED prototypes meeting a rigorous set of performance targets.

The new guidelines in materials’ design and fabrication of LED devices and the enrichment of the available range of materials for the topic provide reliable solutions (with an optimal cost/performance ratio compared to other approaches) to key problems in the field.
