Polyphenylene vinylene (PPV) was the first reported polymer having electroluminescence (EL) properties which made it attractive for light emitting diode (LED) applications. However, low EL efficiency can be observed with ony 0.1% photons/electron. Many efforts were aimed to improve the EL efficiency and stability of PPV such as blending PPV with other polymers. An investigation on the EL and photoluminescence properties of PPV blended with poly(N-vinylpyrolidone) (PVP) is discussed. The prepared polymer blends also behaved like an ionomer which showed local aggregation during aging at room temperature.
