Degradation 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...
متن کاملElectroluminescence in organic light emitting diodes
Principle of electroluminescence The light emission in the presented OLED is based on the formation of electron-hole-pairs within conjugated polymers with semiconducting properties. Therefore a suitable polymer like PPV (fig. 1) has to be placed between a transparent anode and a metallic cathode (fig. 2). By application of an electric voltage electrons (on the cathode side) and holes (on the an...
متن کاملPolarizer-free, high-contrast inverted top-emitting organic light emitting diodes: effect of the electrode structure.
Circular polarizer (CP)-free, high-contrast inverted top-emitting organic light-emitting diodes (ITOLEDs) are demonstrated by using a semitransparent Ag electrode capped with a single dielectric layer as a top anode and Cs(2)CO(3) (1.5 nm)/Al (1.5 nm)/Cr (100nm) as a partially absorbing bottom cathode. Low luminous reflectance is achieved by combining the broadband absorption of Cr, the weak bu...
متن کاملElectron 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...
