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 کاملCatching Thrips (thysanoptera: Thripidae) with Various Traps
Various traps were evaluated for capture of western flower thrips, Franklinella occidentalis (Pergande). More thrips were attracted to blue sticky cards compared with yellow or white cards. With the addition of blue light emitting diodes (LEDs) thrips numbers on blue cards increased 2.2 fold. The numbers of thrips caught per 10cm on blue sticky cups were 2.4 times more than on blue sticky cards...
متن کاملPolarization of III-nitride blue and ultraviolet light-emitting diodes
Polarization-resolved electroluminescence studies of III-nitride blue and ultraviolet sUVd light-emitting diodes sLEDsd were performed. The LEDs were fabricated on nitride materials grown by metalorganic chemical vapor deposition on sapphire substrates s0001d. Transverse electric sTEd polarization dominates in the InGaN/GaN quantum-well sQWd blue LEDs sl8=458 nmd, whereas transverse magnetic sT...
متن کاملIII-nitride blue and ultraviolet photonic crystal light emitting diodes
We present results on enhancement of 460 nm blue and 340 nm UV optical power output in III-nitride light emitting diodes ~LEDs! using photonic crystals ~PCs! under current injection. Triangular arrays of the PCs with diameter/periodicity of 300/700 nm were patterned using electron-beam lithography and inductively coupled plasma dry etching. The total power at 20 mA of 3003300 mm unpackaged LED ...
متن کاملPhosphorescent cyclometalated complexes for efficient blue organic light-emitting diodes
Phosphorescent emitters are extremely important for efficient organic light-emitting diodes (OLEDs), which attract significant attention. Phosphorescent emitters, which have a high phosphorescence quantum yield at room temperature, typically contain a heavy metal such as iridium and have been reported to emit blue, green and red light. In particular, the blue cyclometalated complexes with high ...
