Electron traps in organic light-emitting diodes
This work presents the effects of electron traps in organic light-emitting diodes using a model which includes charge injection, transport, and recombination. For electron-only devices, the electron current is reduced by the traps for several orders of magnitude at fixed voltage, and the traps strongly increase the transient time. For bipolar devices, due to negative trapped charges, traps enha...
متن کاملUsing lithium carbonate-based electron injection structures in high-performance inverted organic light-emitting diodes.
A lithium carbonate-based bi-layered electron injection layer was introduced into inverted organic light-emitting diodes (OLEDs) to reduce operation voltages and achieve carrier balance. Ultraviolet photoemission spectroscopy was used to confirm the existence of an interfacial dipole between the organic and lithium carbonate layers, which is a dominating factor related to the device performance...
متن کاملTemperature dependence of cesium carbonate-doped electron transporting layers on organic light-emitting diodes
The temperature dependence and electronic transport properties of 1, 3, 5-tri(1-phenyl-1H-benzo[d] imidazol-2-yl) phenyl (TPBI) and 8-hydroxyquinoline aluminum (Alq) electron transporting layers (ETL) have been investigated as a function of cesium carbonate (Cs2CO3) doping for organic light emitting devices. The current-voltage and light emission characteristics were measured as a function of t...
متن کاملDegradation in Organic Light Emitting Diodes
The objective is to fabricate organic light emitting diode and to study its degradation process in atmosphere condition in which PFO as an emitting material and PEDOT:PSS as a hole injecting material were used on ITO substrate. Thus degradation process of the OLED was studied upon its current-voltage characteristic. By fabricating this OLED and obtaining blue light and analysis of current-volta...
متن کاملBubble formation in organic light-emitting diodes
Bubbles in organic light-emitting diodes can be formed from gas release due to Joule heating effect at localized electrical shorts during operation, which could be simulated by a rapid thermal annealing. The gases in the bubbles consist of not only adsorbed moistures but also the decomposed organic species, which are detected in situ in an ultrahigh vacuum chamber. In the device of Al/tris-~8-h...
