Electroluminescent characteristics of europium complex thin films prepared using a vacuum deposition technique

Electroluminescent (EL) devices based on organic materials have great interest due to their possible application for large-area flat-panel displays, for which they are attractive because of their multicolor-emission capability and their low operating voltage. In this study, the Electroluminescent (EL) and the current-voltage (I-V) character-istics of Eu(TTA) 3(phen) thin films with various thicknesses from 4 nm to 30 nm and with a structure of …
