Abstract
We have studied organic light-emitting devices (OLEDs) with double-layered inorganic molybdenum trioxide (MoO3)/diamond-like carbon (DLC) as passivation films. The initial device characteristics were identical to those of devices without a passivation film, namely, the maximum luminance and electro luminescence (EL) efficiency were 15,000 cd/m2 and 1.9 lm/W, respectively. However, in the device without a 20 nm MoO3 inorganic film, the device durability was markedly lower than that of the device with a double-layered structure. By adding MoO3 as an additional passivation layer, plasma damage in the peripheral region of the organic layer was markedly reduced, and the resultant device durability was improved significantly.
