    摘要： A multicolor organic light emitting device employs vertically stacked layers of double heterostructure devices which are fabricated from organic compounds. The vertical stacked structure is formed on a glass base having a transparent coating of ITO or similar metal to provide a substrate. Deposited on the substrate is the vertical stacked arrangement of three double heterostructure devices, each fabricated from a suitable organic material. Stacking is implemented such that the double heterostructure with the longest wavelength is on the top of the stack. This constitutes the device emitting red light on the top with the device having the shortest wavelength, namely, the device emitting blue light, on the bottom of the stack. Located between the red and blue device structures is the green device structure. The devices are configured as stacked to provide a staircase profile whereby each device is separated from the other by a thin transparent conductive contact layer to enable light emanating from each of the devices to pass through the semitransparent contacts and through the lower device structures while further enabling each of the devices to receive a selective bias. The devices are substantially transparent when de-energized, making them useful for heads-up display applications.

    摘要： A method for tuning the wavelength of light emitted by an organic light emitting device. An emissive dopant molecule is selected, adapted to emit light when present as a dopant in an emissive layer of the organic light emitting device. The wavelength of light emitted by said emissive dopant molecule depends on the local dipole moment of the emissive layer. The local dipole moment of the emissive layer that would result in said emissive dopant molecule emitting a desired wavelength of light is determined, and an emissive layer is fabricated, doped with the emissive dopant molecule and having the local dipole moment that results in the emissive dopant molecule emitting the desired wavelength of light.

    摘要： A new method for tuning the emission spectrum of OLEDs while retaining a high luminescence efficiency wherein the emission spectrum of a polar luminescent molecule is wavelength shifted by as much as 70 nm when doped into a conductive host in a vacuum-deposited molecular organic light emitting device. The effect may be attributed to changes in the average dipole moment of the host thin film that are induced by the addition of highly dipolar dopant molecules. This phenomenon may be referred to as a “solid state solvation effect” in analogy to similar effects previously identified in solution chemistry. In experiments using singly doped devices, different concentrations of a polar laser dye known as DCM2 are doped in non-polar triaryl amine conductive host films. In these experiments, DCM2 performs the dual role of functioning both as the luminescent center and as the source of the increased spatially averaged dipole moment. In a second set of experiments using dual-doped devices, DCM2 is employed only as the luminescent center in a non-polar host, while a second polar dopant, aluminum tris(8-hydroxyquinoline) (Alq3), is introduced to generate the local dipole moment. By changing the concentration of Alq3, while keeping the DCM2 concentration fixed, the OLED emission may be tuned over a range of 30 nm. For the singly doped devices, the external luminescence quantum efficiency, &eegr;, decreases with dopant concentration due to aggregation induced quenching. However, for the dual-doped devices, &eegr; increases with an increase in the bathochromic shift.

    摘要翻译： 一种用于调节OLED的发射光谱同时保持高发光效率的新方法，其中当在真空沉积的分子有机发光器件中掺杂到导电主体中时，极化发光分子的发射光谱波长偏移多达70nm 。 该效应可归因于通过添加高度偶极掺杂剂分子而诱导的主体薄膜的平均偶极矩的变化。 类似于以前在溶液化学中确定的类似效应，这种现象可称为“固态溶剂化作用”。 在使用单掺杂器件的实验中，将不同浓度的称为DCM2的极性激光染料掺杂在非极性三芳基胺导电性主体膜中。 在这些实验中，DCM2具有作为发光中心和作为增加的空间平均偶极矩的源的双重作用。 在使用双掺杂器件的第二组实验中，DCM2仅用作非极性主体中的发光中心，而第二极性掺杂剂三（8-羟基喹啉）铝（Alq 3）被引入以产生局部 偶极矩 通过改变Alq3的浓度，同时保持DCM2浓度的固定，OLED发射可以调整在30nm的范围内。 对于单掺杂器件，由于聚集诱发的淬火，外部发光量子效率eta随着掺杂剂浓度而降低。 然而，对于双掺杂器件，eta随着红移变化的增加而增加。

    摘要： Organic vertical-cavity surface-emitting lasers ("OVCSELs"), in which a thin layer of organic material is disposed between highly reflective mirrors to thereby form a vertical cavity within a stacked arrangement. The lasers of the present invention each comprise a first mirror layer; a layer of active organic material over the first mirror layer; and a second mirror layer over the layer of first active organic material. The active organic material lases when pumped to thereby produce laser light. The present invention provides for optical semiconductor lasers with desired properties such as narrow bandwidth emission, the minimal use of active organic materials, and the facilitation of wavelength tuning and electrical pumping.
