We demonstrate highly efficient, vapor-deposited blue organic light-emitting diodes (OLEDs) operating at low voltage. For reaching deep-blue color, we used two new fluorophores, 9,10-bis(9,9′-spirobi[9H-fluorene]-2-yl)anthracene (Spiro-Anthracene)

The recent development of polymer light emitting diodes (PLEDs) has triggered a lot of interest for their use in displays, backlights, and for lighting applications. Their high efficiency and ease of manufacturing make PLEDs especially attractive. Va

Transient electroluminescence (EL) from single- and multilayer organic light-emitting diodes (OLEDs) was investigated by driving the devices with short, rectangular voltage pulses. The single-layer devices consist of indium-tin oxide (ITO)/tris(8-hyd

We have performed electric-field and temperature-dependent electron injection studies in an aluminum/tris(8-hydroxy-quinolinolato)aluminum/magnesium:silver single-layer organic light-emitting diode. Analysis of the observed injection currents in term

A novel device structure for organic light-emitting diodes (OLEDs) is described, which consists in the most general case of an alternating sequence of thin inorganic and organic layers sandwiched between two electrodes. Compared to conventional OLEDs

Doped and undoped multilayer organic light-emitting diodes containing copper phthalocyanine as the hole-injection layer, aromatic diamines as the hole-transport layers and (tris(8-hydroxy-quinoline)aluminum) as the electron-injection, electron-transp

Light emitting diodes (LEDs) have been fabricated on the basis of poly-arylenevinylenes substituted at the vinylene double bond and blended with either polycarbonate (PC) or polyvinylcarbazole (PVK). Contacts were indium-tin-oxide (ITO) and aluminum
