Title: Organometallic complexes for use in light emitting devices

Abstract

A new class of organometallic complexes for use in electroluminescent (EL) devices and a method of preparation are disclosed. The organometallic complexes are prepared by mixing organic ligands with metal salts and a layer is formed in an EL device by vacuum evaporation. The organometallic material in the EL device forms a light emission layer.

Organometallic fluorescent complex polymers for light emitting applications

Patent Shi, Song Q.; So, Franky

A fluorescent complex polymer with fluorescent organometallic complexes connected by organic chain spacers is utilized in the fabrication of light emitting devices on a substantially transparent planar substrate by depositing a first conductive layer having p-type conductivity on the planar surface of the substrate, depositing a layer of a hole transporting and electron blocking material on the first conductive layer, depositing a layer of the fluorescent complex polymer on the layer of hole transporting and electron blocking material as an electron transporting emissive layer and depositing a second conductive layer having n-type conductivity on the layer of fluorescent complex polymer.

Organic light-emitting devices using spin-dependent processes

Patent Vardeny, Z Valy [Salt Lake City, UT]; Wohlgenannt, Markus [Salt Lake City, UT]

The maximum luminous efficiency of organic light-emitting materials is increased through spin-dependent processing. The technique is applicable to all electro-luminescent processes in which light is produced by singlet exciton decay, and all devices which use such effects, including LEDs, super-radiant devices, amplified stimulated emission devices, lasers, other optical microcavity devices, electrically pumped optical amplifiers, and phosphorescence (Ph) based light emitting devices. In preferred embodiments, the emissive material is doped with an impurity, or otherwise modified, to increase the spin-lattice relaxation rate (i.e., decrease the spin-lattice time), and hence raise the efficiency of the device. The material may be a polymer,more » « less
