as a transparent anode. In order to validate the accuracy of simulation calculation

MoO

/Ag/MoO

transparent anodes with different thickness of MoO

and Ag films were fabricated. Then

(10 nm)/Ag (10 nm)/MoO

(25 nm)

the device reaches the most optimal performance. The maximum transmittance is 88.256% at 532 nm. And the maximum luminance and luminous efficiency are 20 076 cd/m

and 4.03 cd/A

which are improved by 18.5% and 56% compared with the reference device

respectively. The results demonstrate a practical way to fabricate highly efficient top emitting OLEDs.
