We present the new method to prepare a multi-color electroluminescent device consisting of organic light-emitting-diodes (OLED) and insulating polymeric films. Our multi-color EL device is achieved by three dimensionally superimposed blue-, green-, and red-emitting OLEDs. The interlayer insulation film separated each OLED. These interlayer insulation films prepared by a thermal chemical-vapor-deposition methods are poly-p-xylylene (PPX) and poly-2-chloro-p-xylylene (PCPX). The TCVD polymer films can be prepared at room temperature and in vacuum under a dry process without using organic and aqueous solvents. We demonstrated the two-color emitting OLED (green and orange) by this three-dimensional superimposed method. The structure of lower OLED is glass substrate/ITO (anode)/TPD [50nm]/C540(1mol%)-doped Alq3 [30nm]/Alq3[20nm]/Al (cathode). The structure of top OLED is PPX [0.6 m]/PCPX [0.6 m]/IDIXO (anode)/TPD [50nm]/DCM(1mol%)-doped Alq3 [30nm]/Alq3 [20nm]/AlLi (cathode). We used InィイD22ィエD2OィイD23ィエD2-ZnO thin films were deposited on PPX (having OLEDs) at room temperature in a dc magnetron sputtering method. We used InィイD22ィエD2OィイD23ィエD2-ZnO thin films were deposited on PPX (having OLEDs) at room temperature in a dc magnetron sputtering method. When this multi-layer device were independently driven in applied voltage, this device emitted green- and orange-lights. The EL characteristics of OLEDs were not influenced by process of TCVD polymer film the preparation. In addition, we succeed to prepare three-color (R, G, B) emitting OLEDs by using this method. Our proposing method is very effective and practical for the formation of a color device.

本文提出了一种制备多色有机电致发光器件的新方法，该器件由有机电致发光器件和绝缘聚合物薄膜组成。我们的多色EL器件是通过三维叠加的蓝色、绿色和红色发光OLED实现的。层间绝缘膜分隔每个OLED。通过热化学气相沉积方法制备的这些层间绝缘膜是聚对二甲苯（PPX）和聚2-氯对二甲苯（PCPX）。TCVD聚合物膜可以在室温和真空下在干法下制备，而不使用有机溶剂和水溶剂。我们用这种三维叠加的方法制作了绿色和橙子双色发光的有机电致发光器件。下层OLED的结构为玻璃衬底/ITO（阳极）/TPD [50 nm]/C540（1mol%）掺杂Alq 3 [30 nm]/Alq 3 [20 nm]/Al（阴极）。顶部OLED的结构为PPX [0.6 m]/PCPX [0.6 m]/IDIXO（阳极）/TPD [50 nm]/DCM（1mol%）-掺杂Alq 3 [30 nm]/Alq 3 [20 nm]/AlLi（阴极）。我们采用直流磁控溅射方法在室温下在PPX（具有OLED）上沉积In掺杂D22掺杂D2 O掺杂D23掺杂D2-ZnO薄膜。我们采用直流磁控溅射方法在室温下在PPX（具有OLED）上沉积In掺杂D22掺杂D2 O掺杂D23掺杂D2-ZnO薄膜。当该多层器件在外加电压下独立驱动时，该器件发射绿色和橙色光。TCVD聚合物薄膜的制备工艺不影响OLED的EL特性。此外，我们还成功地用这种方法制备了三色（R，G，B）发光器件。我们提出的方法对于形成彩色器件是非常有效和实用的。
