Blue Organic Light-Emitting Diodes with External Quantum Efficiencies over 20% Based on Europium(II) Emitters
Mahmoud Soleimani, Toni Bärschneider, Felix Kaden +4
The realization of blue electroluminescence with high efficiency and lifetime remains a long-standing hurdle for organic light-emitting diode (OLED) technology to overcome. Divalen…
High-Efficiency Deep Blue Single-Gaussian Europium(II) Emitters and their Emitter-Host Interactions
Mahmoud Soleimani, Paulius Imbrasas, Jan-Michael Mewes +6
Eu(II) complexes are attractive emitters for deep-blue organic light-emitting diodes (OLEDs) due to their narrow, parity-allowed 4f-5d emission; however, their implementation in va…
