چکیده

Inverted top-emitting organic light-emitting devices (ITOLEDs) employing thin film of vanadium pentoxide (V2O5) capped with vacuum deposited semitransparent silver layer as top anode were studied. The devices consisted of C-545T doped in Alq3 as emitting layers exhibited a maximum external current efficiency of ~11cd/A and a turn on voltage of ~6.4V.We attribute the good performance of the devices to the high work function of V2O5 which provides efficient hole injection into the devices.

4.2: Highly Efficient Top-Emitting White Organic Electroluminescent Devices

We have developed highly efficient white top-emitting organic light-emitting devices (TOLEDs) with broad emission by modifying both anode and cathode. To alleviate the undesirable microcavity effect and obtain “broad” white emission, CFxcoated Ag anode with modified reflectivity and an index-matching layer (SnO2) capped on thin Ca/Ag cathode with a maximal transparency of 80% were employed. A t...

Thin-film Encapsulation of Organic Light-Emitting Diodes Using Single and Multilayer Structures of MgF2, YF3 and ZnS

In this research, the lifetime of green organic light emitting diodes (OLEDs) is studied using four passivation layers. To encapsulate the OLEDs, MgF2, YF3, composed of alternating MgF2/ZnS and YF3/ZnS layers were grown by thermal vacuum deposition. Measurements show that the device lifetime is significantly improved by using YF3 and ZnS as passivation layers. However, diodes encapsulated by Mg...

Investigation of top-emitting organic light-emitting devices with highly saturated color employing metal-mirror structure

In this work, characteristics of top-emitting organic light-emitting devices (TEOLEDs) having Ag and Au as anode had been investigated. When using the same emitting materials, the performance of TEOLEDs employing Ag as anode was superior to that of the device using Au as anode. Finally, by using the appropriate dopant instead of Alq as emitter, a TEOLED with high power efficiency (8.7 lm/w with...
