Abstract

Transparent metal cathodes using Ca/Ag, Ba/Ag double layers have been fabricated to investigate its optical transmission. The transmission spectra show that Ca/Ag and Ba/Ag double layers result in higher transmittance compared to Ag single layer. The Ba/Ag double layer shows over 80% transmittance at 400 nm and 70% at 700 nm. The electroluminescence efficiency of fluorescent TEOLED using Ba/Ag transparent metal cathode was 10 ~ 15 cd/A.
