Highly efficient and air-stable Eu(II)-containing azacryptates ready for organic light-emitting diodes

Nature Communications, 2020
Though divalent-europium-based complexes are promising materials for next-generation light-emitting devices, their poor air stability limits their applicability.

All-fluorescence white organic light-emitting diodes with record-beating power efficiencies over 130 lm W‒1 and small roll-offs

Nature Communications, 2022
High power efficiency and low roll-off values are essential to the commercialization of white organic light-emitting diodes. Here, the authors construct all-fluorescence devices with an orange emitting layer sandwiched between two sky-blue emitting ...

Printed Nanostructures for Organic Photovoltaic Cells and Solution‐Processed Polymer Light‐Emitting Diodes [PDF]

, 2015
We review the progress on printing‐based technologies for organic electronic devices, especially organic photovoltaic (OPV) cells and polymer light‐emitting diodes (PLEDs). First we discuss recent efforts to introduce interdigitated nanostructures on the

Optimization of organic light emitting diode structures [PDF]

SPIE Proceedings, 2004
In this work we present detailed analysis of the emitted radiation spectrum from tris(8-hydroxyquinoline) aluminum (Alq3) based OLEDs as a function of: the choice of cathode, the thickness of organic layers, and the position of the hole transport layer/Alq3 interface.

Enhanced flexible optoelectronic devices by controlling the wettability of an organic bifacial interlayer

Communications Materials, 2021
A challenge for optoelectronic devices is the differing wettability of the organic active layer and transparent electrodes. Here, an organic interlayer which is hydrophilic or hydrophobic on each side enhances the performance of organic photovoltaic ...

Comparison of ophthalmic toxicity of light-emitting diode and organic light-emitting diode light sources [PDF]

Scientific Reports, 2020
AbstractThe use of organic light-emitting diodes (OLEDs) has rapidly increased in recent years. However, the effect of OLEDs on human health has not been studied yet. We investigated morphologic and functional changes after OLEDs exposure of human ocular cells, including corneal, conjunctival, lens, and retinal pigment epithelial cells, and mouse eyes.

Multiresonant Thermally Activated Delayed Fluorescence Emitters Based on Heteroatom‐Doped Nanographenes: Recent Advances and Prospects for Organic Light‐Emitting Diodes

Advanced Functional Materials, 2020
Since the first report in 2015, multiresonant thermally activated delayed fluorescent (MR‐TADF) compounds, a subclass of TADF emitters based on a heteroatom‐doped nanographene material, have come to the fore as attractive hosts as well as emitters for ...
