摘要:
A method of production of a thin film electroluminescent device comprising the steps of: providing a substrate; providing a conductor on the substrate; providing a dielectric layer on the conductor; providing a phosphor layer on the dielectric layer so creating a phosphor/dielectric interface region, the phosphor/dielectric region interface comprising a plurality of electron interface states; and transiently laser annealing the phosphor layer so as to induce an in depth annealing effect to the phosphor layer without heating the phosphor/dielectric region above a temperature which includes a substantial modification in the distribution of electron interface states.
摘要:
A thin film electroluminescent device, comprising a first electrode layer, first and second dielectric layers with an active phosphor layer disposed therebetween, and a second electrode layer, wherein there is provided within the phosphor layer at least one barrier layer comprising a thin layer of dielectric material. An array of such devices placed side to side is provided with a print head suitable for A4 electrographic printing.
摘要:
A thin film comprising a layer of dielectric material having electrically conductive inclusions, wherein the thin film has a first reflectivity due to surface plasmon resonance, and wherein the thin film is configured to provide one or more selected regions having a second reflectivity due to surface plasmon resonance.
