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

Creating highly efficient stretchable OLEDs with nanowavy structures for angle-independent narrow band emission

npj Flexible Electronics
Stretchable organic light-emitting diodes (SOLEDs) have been the challenging class of OLEDs as they have limited processability to fabricate a design that can withstand external deformation.

Electron correlation effects in electron-hole recombination in organic light-emitting diodes [PDF]

, 2002
We develop a general theory of electron--hole recombination in organic light emitting diodes that leads to formation of emissive singlet excitons and nonemissive triplet excitons.

Dual-color emissive OLED with orthogonal polarization modes

Nature Communications
Linearly polarized organic light-emitting diodes have become appealing functional expansions of polarization optics and optoelectronic applications. However, the current linearly polarized diodes exhibit low polarization performance, cost-prohibitive ...

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.
