AC-driven, color-and brightness-tunable organic light-emitting diodes constructed from an electron only device

Zhao, Y.; Chen, R.; Gao, Y.; Leck, K.S.; Yang X.; Liu, S.; Abiyasa, A.P.; Divayana, Y.; Mutlugun, E.; Tan, S.T.; Sun H.; Demir, Hilmi Volkan; Sun X.W. (2013)

In this paper, a color- and brightness-tunable organic light-emitting diode (OLED) is reported. This OLED was realized by inserting a charge generation layer into an electron only device to form an n-i-p-i-n structure. It ...
Nanocrystal LEDs with enhanced external quantum efficiency enabled by the use of phosphorescent molecules

Mutlugün, Evren; Abiyasa, A.P.; Güzeltürk, Burak; Gao, Y.; Leck, K.S.; Sun X.W.; Demir, Hilmi Volkan (IEEE, 2013)

We report efficiency enhancement in quantum dot (QD) based LEDs with the aid of excitonic energy transfer from co-doped TCTA:Ir(ppy)3 layer to CdSe/ZnS QDs while providing spectrally pure emission. © 2013 IEEE.
