Abstract

The multi-layer microcavity OLEDs have been fabricated with hole transport layers of CBP and TCTA

an emissive layer of Eu(DBM)

Bath

and an electron transport layer of TPBI. Multicolor electroluminescence from the transition of Eu

iron with three peaks at 580 nm (

)

612 nm (

)

and 652 nm (

) was achieved by changing the transition rate between the different energy levels of Eu(DBM)

Bath through optical microcavity. The microcavity OLED device with an EL peak of 612 nm shows the maximum current efficiency more than 20 cd/A

and maximum luminance over 1 300 cd/m
