The degradation process of a single layer electroluminescence (EL) polymer MEH-PPV organic light emitting diode (OLED) with the MEH-PPV thickness of 57plusmn3 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...
