End-emitting nano organic light emitting diodes (OLEDs) with directional output

Nanophotonics, 2020
We report a new strategy for the design of organic light emitting diodes (OLEDs), where nanoscale OLEDs are fabricated into a large-area periodic array with their emission propagating along the active layer and being coupled out through the end facets. A

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.
