Paper Abstract

In this work structural composition and fabrication process of cathode for transparent OLED were investigated. Using a LiF/Al/Ag/Alq3 semitransparent cathode and a Mg:Ag/ITO cathode, green fluorescent transparent organic light-emitting devices (TOLEDs) were fabricated. ITO was evaporated as a cathode onto a thin Mg:Ag layer by DC magnetron sputtering method with the assistance of tiny H2O vapor during deposition process. The fabrication of LiF/Al/Ag/Alq3 electrode was processed without breaking the vacuum. At a bias of 15 V, the luminance of the TOLED with Mg:Ag/ITO and LiF/Al/Ag/Alq3 cathode were 3016 and 4535 cd/m2, respectively. The results indicate that LiF/Al/Ag/Alq3 electrode can be used as an effective and stable cathode in TOLEDs.
