The optical and electrical properties of polymer composite films based on poly(2-methoxy-5-dodecyloxy-p-phenylenevinylene) (MDDOPPV) and poly(9,9-dioctylfluorene-co-benzothiadiazole) (F8BT) have been studied. The optical properties. such as, absorption and photoluminescence (PL) spectra, PL efficiency, and PL lifetime of the polymer composite films, have been clarified. Utilizing the polymer composite thin film consisting of 50%-F8BT as an emission layer, the multimode lasing from a microcapillary structure with low threshold energy by pulsed photo-pumping and the high current density injection have been demonstrated.
