Abstract
Abstract
The energy transfer in a blend of conducting polymers, poly[9-vinylcarbarzole] (PVK) and poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV), was investigated. Energy transfer from PVK to MEH-PPV leads to enhanced emission of MEH-PPV. Photoluminescence (PL) of the nanocomposite of TiO
2 and the blended polymer films was enhanced as the relative content of TiO
2 was increased, and, in particular, the most improved PL was observed for the optimal ratio of TiO
2 and these films emitted green light. These results provide further insight into the photophysics of conjugated polymers and the improvement of the current–voltage (I–V) characteristics of the devices based on blended conducting polymer systems.
