    摘要： An OLED may include regions of a material having a refractive index less than that of the substrate, or of the organic region, allowing for emitted light in a waveguide mode to be extracted into air. These regions can be placed adjacent to the emissive regions of an OLED in a direction parallel to the electrodes. The substrate may also be given a nonstandard shape to further improve the conversion of waveguide mode and/or glass mode light to air mode. The outcoupling efficiency of such a device may be up to two to three times the efficiency of a standard OLED. Methods for fabricating such a transparent or top-emitting OLED is also provided.

    摘要翻译： OLED可以包括具有小于衬底或有机区域的折射率的材料的区域，从而允许波导模式中的发射光被提取到空气中。 这些区域可以在与电极平行的方向上与OLED的发射区域相邻放置。 衬底也可以被赋予非标准形状，以进一步改善波导模式和/或玻璃模式光到空气模式的转换。 这种器件的输出耦合效率可高达标准OLED效率的两到三倍。 还提供了制造这种透明或顶部发光OLED的方法。

    摘要： An optoelectronic device may be fabricated on a three dimensional surface by transferring a material from an elastomeric stamp to a non-planar substrate. The use of an elastomeric stamp allows for patterned layers to be deposited on a non-planar substrate with reduced chance of damage to the patterned layer. The material may be deposited on the stamp while the stamp is in a planar configuration or after the stamp has been deformed to a shape generally the same as the shape of the non-planar substrate. The material may be transferred by cold welding. The device may include organic layers.

    摘要： A method which lower the series resistance of photosensitive devices includes providing a transparent film of a first electrically conductive material arranged on a transparent substrate; depositing and patterning a mask over the first electrically conductive material, such that openings in the mask have sloping sides which narrow approaching the substrate; depositing a second electrically conductive material directly onto the first electrically conductive material exposed in the openings of the mask, at least partially filling the openings; stripping the mask, leaving behind reentrant structures of the second electrically conductive material which were formed by the deposits in the openings of the mask; after stripping the mask, depositing a first organic material onto the first electrically conductive material in between the reentrant structures; and directionally depositing a third electrically conductive material over the first organic material deposited in between the reentrant structures, edges of the reentrant structures aligning deposition so that the third electrically conductive material does not directly contact the first electrically conductive material, and does not directly contact the second electrically conductive material.

    摘要： An unipolar organic injection laser in which electrically-stimulated intraband transitions result in lasing. An active region includes at least one organic injector layer and at least one organic emitter layer. Each organic emitter layer has a first energy level and a second energy level on a same side of an energy gap defined by a conduction band and a valance band. Charge carriers are injected through the organic injector layer into the first energy level of the organic emitter layer when a voltage is applied across active region. The difference in energy between the first and second energy levels produces radiative emissions when charge carriers transition from the first energy level to the second energy level. Population inversion is maintained between the first and second energy levels, producing stimulated emission and lasing.
