摘要
The degradation process of a single layer electrolumineseence (EL) polymer MEH-PPV Organic Light Emitting Diode (OLED) with the MEH-PPV thickness of 57 3 nm is discussed. Typical structure of OLED fabrication is Al/MEH-PPV/ITO (Indium Tin Oxide). Electroluminescence (EL) spectrum indicates that the emission of MEH-PPV device is the yellow orange color. The device degrades by days as demonstrated by the increased in the turn on voltage obtained from I/V curves. The Scanning Electron Microscope (SEM) images show some bubbles emerge on the surface of the device after an electric field was applied to it.
