Emission mechanism in OELD : Shift from green to blue
Abstract
Organic electroluminescent devices (OELDs) with the structure of ITO/TPD/PBD/Alq 3 /Al:Li were fabricated and the effects of applied voltage, thickness of organic layer and ITO anode to probe the emission mechanism was investigated. EL spectra and CIE coordinates of these devices were measured to observe emitting characteristics in various voltages and it was observed that the emission color gradually changes from yellowish-green to …
