We designed and synthesized a new organic light-emitting diode (OLED) emitter, SBABz4, containing spiro-biacridine donor (D) in the core surrounded by two benzonitrile acceptors (A). The dual A-DxD-A structure is shown to provide pure-blue emission in rela ...
The development of transition metal complexes for application in light-emitting devices is currently attracting significant research interest. Among phosphorescent emitters, those involving iridium (III) complexes have proven to be exceedingly useful due t ...
The electroluminescence of organic films is the central aspect in organic light emitting diodes (OLEDs) and widely used in current display technology. However, its spatial variation on the molecular scale is essentially unexplored. Here, we address this is ...
In this thesis work we explore spin dependent processes and charge dynamics in α-NPD/Alq₃ based LEDs. Studies on polymer light emitting diodes based on PFO, which are fabricated by us, are also reported. Our objective is to shed light on the fundamental me ...
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 ...
Laser-induced forward transfer (LIFT) is a versatile organic light-emitting diode (OLED) pixel deposition process, but has hitherto been applied exclusively to polymeric materials. Here, a modified LIFT process has been used to fabricate small molecule Alq ...
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 ...
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 ...
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 ...
Magnetic field effects on the conductivity of different types of organic devices: undoped and dye doped aluminium (III) 8-hydroxyquinoline (Alq3)-based organic light emitting diodes (OLEDs), electrononly Alq3-based diodes, and a hole-only N,N'-diphenyl-N,N ...
