Precise Evaluation of Angstrom-Ordered Mixed Interfaces in Solution-Processed OLEDs by Neutron Reflectometry, Satoru Ohisa, Go Matsuba, Norifumi Yamada, Yong-Jin Pu, Hisahiro Sasabe, Junji Kido, Adv. Mater. Inter. in press.

 

Abstract: The interfaces between hole-transporting polymer (TFB) and the emitting small molecules (CBP: Ir(ppy)3) in OLEDs are investigated using neutron reflectometry. The interface with the evaporated CBP: Ir(ppy)3 layer is clear. On the other hand, the interface with the spin-coated CBP: Ir(ppy)3 layer is broad, and the CBP: Ir(ppy)3 disperses into the TFB layer. The mixing ratio of CBP is larger than that of Ir(ppy)3. The influences of the interfaces on the hole only device characteristics are investigated.

 

大久さん、おめでとうございます!
