摘要： A light source comprises an organic light-emitting device, which emits radiation having a first spectrum, and a phosphor layer, which absorbs a portion of the light emitted by the organic light-emitting layer and which emits light having a second spectrum. The organic light-emitting device comprises an organic light-emitting layer disposed between a pair of electrodes, and at least a charge-blocking layer disposed between the organic light-emitting layer and one of the electrodes. The phosphor layer typically absorbs less than all of the light emitted by the organic light-emitting layer and typically covers the entire organic light-emitting device. The light emitted by the organic light-emitting layer is mixed with the light emitted by the phosphor layer to produce light having a third spectrum.

摘要： A light source comprises an organic light emitting device which emits radiation having a first spectrum and a phosphor layer which absorbs a portion of the light emitted by the organic light emitting layer and which emits light having a second spectrum. The phosphor layer typically absorbs less than all of the light emitted by the organic light emitting layer and typically covers the entire organic light emitting device. The light emitted by the organic light emitting layer is mixed with the light emitted by the phosphor layer to produce light having a third spectrum. Exemplary embodiments of the invention provide advantages over known devices. For example, because a phosphor layer is provided, the light emitted from the organic light emitting device is scattered, which provides improved uniformity in light output over the area of the light source. Also, because most phosphors are relatively stable over time, the light source has good color stability over time.

摘要： The invention relates to a luminescent display comprising a first electrode, a second electrode, an organic light emitting layer disposed between the first and second electrodes, and a luminescent material which receives light from the organic light emitting layer and converts the light to a different wavelength, wherein the first and second electrodes together define an overlap region in which the organic light emitting layer is activated to emit light, and the luminescent material is disposed in a portion of the overlap region. The invention also relates to a method comprising the steps of creating an image and printing the image on a light emitting device comprising an organic light emitting layer after the light emitting device has been formed. The image may be created, for example on a personal computer, and printed with an inkjet printer. The image may be printed in phosphors which emit light of one wavelength upon absorbing light of a different wavelength from the organic light emitting layer. Various embodiments of the invention allow customized luminescent displays to be easily fabricated by end users by applying a phosphor pattern to a preformed, encapsulated light emitting device.

Also, a light emitting apparatus is disclosed which comprises at least one of a red, green and blue phosphor for absorbing and converting ultraviolet radiation from a light emitting semiconductor into visible light. A laser diode can be used to activate the phosphors to provide improved efficiency and brightness.

摘要： A current limiting device comprises at least two electrodes; an electrically conductive composite material between the electrodes; interfaces between the electrodes the said composite material; and an inhomogeneous resistance distribution structure at the interfaces. During a high current event, adiabatic resistive heating at the interfaces causes rapid thermal expansion and vaporization and at least a partial physical separation at the interfaces; so the resistance of the current limiting device increases. The composite material comprises at least one polymeric matrix material and at least one electrically conductive material, and the polymeric matrix material comprises at least one epoxy and at least one silicone.

摘要： An energy storage device includes a housing having an interior surface defining a volume and a plurality of solid electrolyte elements disposed in the volume. Each solid electrolyte element has a first surface that defines at least a portion of a first, cathodic chamber, and a second surface that defines a second, anodic chamber. A plurality of individual anodic chambers are thus provided, at least one of which is evacuated below atmospheric pressure. A majority of anodic chambers can be spaced from one another in a manner that provides a substantially uniform reaction rate throughout the cathodic chamber. The housing and the plurality of solid electrolyte elements together may be configured to define a second volume devoid of solid electrolyte elements and that is sufficient in size to accommodate a desired number of solid electrolyte elements and to provide an accessible cathodic chamber filling point and that is further sufficient in size to alter the volume of the cathodic chamber with respect to the volume of the plurality of anodic chambers to achieve a desired volumetric ratio between the cathodic and anodic chambers.
