The article "Inkjet Printing of Super Yellow: Ink Formulation, Film Optimization, OLEDs Fabrication, and Transient Electroluminescence" from Amruth C (PhD 9, Technical University of Lodz), Marek Zdzislaw Szymanski, Prof Jacek Ulanski (TUL), Dr Beata Luszczynska (TUL) has recently been published in Nature's Scientific Reports.
The inkjet printing technique allows the manufacturing of low-cost organic light emitting diodes (OLEDs) in ambient conditions, and can result in an OLEDs fabrication process that is faster than conventionally used vacuum-based processing techniques. The paper details the use of inkjet printing technique to investigate the formation of thin active layers of the Super Yellow (poly(para-phenylene vinylene) copolymer), a well-known light emitting polymer material. The performance of the fabricated OLEDs was remarkable and the methodologic process can be used to obtain efficient printed OLEDs in both academic and in industrial settings.
