Failure of the top emission organic light-emitting device with a Ca/Ag semitransparent cathode

The influence of vacuum conditions during the deposition of Ca/Ag cathode on the performance of top emission organic light-emitting devices (TEOLEDs) is investigated. The fabricated devices have been characterized by current–voltage ( I– V) and electroluminescence (EL) measurements. Low turn-on volt...

Description
Summary:The influence of vacuum conditions during the deposition of Ca/Ag cathode on the performance of top emission organic light-emitting devices (TEOLEDs) is investigated. The fabricated devices have been characterized by current–voltage ( I– V) and electroluminescence (EL) measurements. Low turn-on voltage and high yield of EL are observed if the cathode is deposited in a better background pressure than 2.78 × 10 −6 Torr, whereas the deposition of cathode in a poor back ground pressure (
