Optical and electrical properties of composites formed by mixing porous silicon (PS) and poly (9, 9-diocty-2, 7-fluoreneco-4, 4’-butoxydiphenyl) (PFP) have been studied by Fourier transform-infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and photoluminescence (PL) spectroscopy. The optical spectra show that porous silicon is incorporated into the polymer without significant change in the polymer properties. The FT-IR spectroscopy has detected the existence of specific interactions, which may be attributed to non-conjugated alkoxy segment. By fitting the current-voltage (I-V) curve of PFP/PS structure with the modified standard equation, the n factor and I0 are determined.
Optical and electrical properties of composites formed by mixing porous silicon (PS) and poly (9,9-diocty-2, 7-fluoreneco-4, 4’-butoxydiphenyl) (PFP) have been studied by Fourier transform-infrared spectroscopy -IR), scanning electron microscopy (SEM) and photoluminescence (PL) spectroscopy. The optical spectra show that porous silicon is incorporated into the polymer without significant change in the polymer properties. The FT-IR spectroscopy has detected the existence of specific interactions, By fitting the current-voltage (IV) curve of PFP / PS structure with the modified standard equation, the n factor and I0 are determined.
