Abstract: We analyzed the structure of buried interface of BBDMS-PPV/ITO system using a high resolution ADXPS technique. A transitional layer structure, whose chemical composition, state and valence band changed gradually from BBDMS-PPV surface of film to substrate ITO, was observed. It was found that O2- ion from ITO diffused into polymer film, interacted with back-bone carbon and formed the carbonyl bonding which could possibly constructed the channel of the carrier on the heterointerface. Indium of ITO also diffused into BBDMS-PPV layer and In(OH)3 was formed during diffusion. The diffusion and reaction between PPV/ITO interface may affect the performance of PLED significantly.
