摘要:
An organic light emissive device, which comprises: an anode; a cathode; and an organic light emissive region between the anode and the cathode, which region comprises: a layer of blue light electroluminescent organic material which emits light having first CIE co-ordinates by exciton radiative decay; and a layer of longer wavelength electroluminescent organic material which intrinsically emits light having second CIE co-ordinates by exciton radiative decay; wherein the layers of blue light and longer wavelength materials are selected so that the organic light emissive region emits white light falling within a region having a CIE χ coordinate equivalent to that emitted by a black body at 3000-9000K and CIE γ co-ordinate of said light emitted by a black body.

摘要:
A method of forming an organic light emitting diode comprising the steps of: providing a substrate comprising a first electrode for injection of charge carriers of a first type; forming a charge transporting layer by depositing over the substrate a charge transporting material for transporting charge carriers of the first type, the charge transporting material being soluble in a solvent; treating the charge transporting layer to render it insoluble in the solvent; forming an electroluminescent layer by depositing onto the charge transporting layer a composition comprising the solvent, a phosphorescent material, and a host material; and depositing over the electroluminescent layer a second electrode for injection of charge carriers of a second type.
