The aim of the project is to develop an innovative technology for printing multilayer light emitting diodes with an emission layer based on environmentally friendly quantum dots (QD-LED). Quantum dots (QDs) are a promising class of emissive compounds that can be processed by solution techniques. Additionally, QDs exhibit unique characteristics such as narrow photoluminescence spectra, pure colours and ease of tuning the emission maximum, explains Assoc. Professor Beata Łuszczyńska from the Faculty of Chemistry of TUL, the project leader.
The application of the new jet printing technology with innovative use of an electron injection layer will allow to easily obtain light emitting surfaces of any patterns without the need to use vacuum vaporization and shadow masks.
The objective of the research and implementation project will be achieved through the cooperation of Polish and German research units - Lodz University of Technology and Fraunhofer Institute for Applied Polymer Research from Potsdam-Golm, as well as industrial partners - QWERTY from Lodz and ALLRESIST GmbH from Strausberg.
The project partners have complementary competences and extensive experience in the development of inks, printing technologies and the production and testing of light-emitting diodes. Such a solution will reduce production costs and ensure significant progress in manufacturing high-efficiency QD-LEDs with a broad spectrum of applications, such as lighting panels, information or advertising boards, informs Prof. Łuszczyńska, Head of the Department of Molecular Physics, TUL.
