Abstract
Optical properties of composite films formed by mixing poly (p phenylene vinylene) and porous silicon (PPV/PS) with various concentrations were investigated by Raman, infrared (IR) and photoluminescence (PL) spectroscopy. Analysis of the Raman and IR spectra showed that PS was incorporated to the polymer matrix without effecting its properties. Modifications of the PL spectra were explained by the presence of oxygen from the PS grains. Light emitting diodes (LEDs) using the composite as an emitter exhibited low turn-on voltage as compared to PPV based devices.
