Laser-induced forward transfer (LIFT) has already been used to fabricate various types of organic light-emitting diodes (OLEDs), and the process itself has been optimised and refined considerably since OLED pixels were first demonstrated. In particular, a ...
Electrically Detected Magnetic Resonance (EDMR) was used to investigate the influence of dye doping on spin-dependent exciton formation in aluminum (III) 8-hydroxyquinoline (Alq(3)) based Organic Light Emitting Diodes (OLEDs) with different device structur ...
Light-emitting devices that utilize thin films of metal nanoclusters as quantum emitters are presented. Implementing Ag as well as Au nanoclusters, the versatility of the approach is demonstrated, and it is shown that the electroluminescence measured from ...
Electronic devices based on organic semiconductors, such as field-effect transistors (OTFTs) and organic diodes have attracted significant interest as possible inexpensive and flexible alternatives to inorganic devices. Despite considerable improvement in ...
Carbazole, a commonly used hole-transporter for organic electronics, has been modified with an imidazolium cation and a hexafluorophosphate counter-anion to give an ionic hole-transporter. It has been applied as one of the hosts in a host-guest blue light- ...
Patterned deposition of polymer light-emitting diode (PLED) pixels is a challenge for electronic display applications. PLEDs have additional problems requiring solvent orthogonality of different materials in adjacent layers. We present the fabrication of a ...
Recent startling interest for lanthanide luminescence is stimulated by the continuously expanding need for luminescent materials meeting the stringent requirements of telecommunication, lighting, electroluminescent devices, (bio-)analytical sensors and bio ...
In light-emitting electrochemical cells, the lifetime of the device is intrinsically linked to the stability of the phosphorescent emitter. In this study, we present a series of ionic iridium(III) emitters based on cyclometalating phenylpyridine ligands wh ...
The aim of the present work is to investigate the nature of spin dependent processes in an organic light emitting diode based on a ITO/α-NPD/Alq3 structure. The electroluminescence time response of the sample is monitored while the OLED is exposed to a hig ...
Using pulsed electroluminescence detected magnetic resonance (PELDMR), we study the dynamics of spin processes in Alq(3) based light-emitting diodes. The transitions induced by magnetic resonance are found to be much faster than the space charge reaction t ...
