Development of full-color organic El devices using interlayer of thermal CVD polymer

我们现在有一个新方法来预pare一个multi-color electroluminescent device consisting of ganiclight-emitting-diodes （OLED）和insulating polymeric films. Our multi-color EL device is achievedby three dimensionally superimposed blue-, green-，and red-emitting OLEDs. The interlayer insulation film separated each OLED. These interlayerinsulation 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 andin vacuum under a dry process without using organic and aqueous solvents. We demonstrated thetwo-color emitting OLED (green and orange) by this three-dimensional superimposed method. Thestructure 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 usedD22 D2O D23 d02 - zno thin films were deposited on PPX (having OLEDs) at room temperature In adc magnetron sputtering method. We used In D22 D2O D23 D2-ZnO thin films were deposited on PPX（having OLEDs） at room temperature in a dc magnetron sputtering method. When this multi-layer devicewere independently驱动in applied voltagethis device emitted green and orange-lights. The EL characteristics of OLEDs not influenced by过程TCVD polymer film the preparation. In addition, we succeed to prepare three-color （R， R）g,B) emitting OLEDs by using this method. Our proposing method是非常有效和实用的formation of a color device。
