Silver Nanowires Modified with PEDOT: PSS and Graphene for Organic Light-Emitting Diodes Anode
Silver nanowires (AgNWs) networks are promising candidates for the replacement of indium tin oxide (ITO). However, the surface roughness of the AgNWs network is still too high for its application in optoelectronic devices. In this work, we have reduced the surface roughness of the AgNWs networks to 6.4 nm, compared to 33.9 nm of the as-deposited AgNWs network through the hot-pressing process, t...
متن کاملHigh efficiency green phosphorescent top-emitting organic light-emitting diode with ultrathin non-doped emissive layer
Ultrathin non-doped emissive layer (EML) has been employed in green phosphorescent top-emitting organic light-emitting diodes (TOLEDs) to take full advantages of the cavity standing wave condition in a microcavity structure. Much higher out-coupling efficiency has been observed compared to conventional doped EML with relatively wide emission zone. A further investigation on dual ultrathin non-d...
متن کاملP-128: Inverted Top-Emitting Organic Light-Emitting Devices Using Vanadium Pentoxide as Anode Buffer Layer
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 devi...
متن کاملExtremely efficient flexible organic light-emitting diodes with modified graphene anode
Although graphene films have a strong potential to replace indium tin oxide anodes in organic light-emitting diodes (OLEDs), to date, the luminous efficiency of OLEDs with graphene anodes has been limited by a lack of efficient methods to improve the low work function and reduce the sheet resistance of graphene films to the levels required for electrodes1–4. Here, we fabricate flexible OLEDs by...
متن کاملMicro-Cavity in Organic Light-Emitting Diode
The study on micro-cavity in organic light-emitting diode(OLED) demands understanding the theory of multi-layer films. It is because OLED is basically an optical device and its structure consists of organic or inorganic layers of sub-wavelength thickness with different refractive indices. When the electron and holes are injected through the electrodes, they combine in the emission layers emitti...
