ORGANIC LIGHT EMITTING DIODES (OLED)
Annals of the Academy of Romanian Scientists Series on Physics and Chemistry, 2023 "Organic Light Emitting Diodes (OLED) now reach the third phase concerning efficiency. The first devices are based on pure organic materials, and the second and third generations are based on combinations between metals and organic ligands in so- called organometallics for which their emission external quantum efficiency is increased.

Enhanced light emission from top-emitting organic light-emitting diodes by optimizing surface plasmon polariton losses [PDF]
, 2015 We demonstrate enhanced light extraction for monochrome top-emitting organic light-emitting diodes (OLEDs). The enhancement by a factor of 1.2 compared to a reference sample is caused by the use of a hole transport layer (HTL) material possessing a low ...

Beyond the Edge: Charge‐Transfer Excitons in Organic Donor‐Acceptor Cocrystals
Advanced Functional Materials, EarlyView.Complex excitonic landscapes in acene–perfluoroacene cocrystals are unveiled by polarization‐resolved optical spectroscopy and many‐body theory. This systematic study of a prototypical model system for weakly interacting donor–acceptor compounds challenges common views of charge‐transfer excitons, providing a refined conceptual framework for ...
