Abstract

The solution of poly[(9,9-di-n-octylfluorenyl-2,7-diyl)-alt-(benzo[2,1,3]thiadiazol-4,8-diyl)] (F8BT) F8BT/TiO2 nanocomposites were prepared using solution blending methods. The TiO2 contents were fixed between 0 wt%-35 wt%. Then, the solutions were spin coated at 1000 rpm for 30 s onto glass substrates to form thin film samples. The optical properties of the nanocomposites were determined using UV-Vis spectroscopy and photoluminescence spectroscopy. The absorption properties of the thin film increased due to existence of intermediate energy band which lead to higher space charge regions for electron insertion. Besides that, the λmax for absorption and emission spectrum were systematically shifted due to incorporation of TiO2 NPs indicating an interaction between nanoparticles and polymer matrix. Furthermore, the intensity of the emission spectrum was enhanced in the presence of TiO2 NPs. This is due to the existence of TiO2 NPs which trapped more electrons at the interface F8BT/TiO2, resulted production of higher number of exciton formation in the nanocomposirte samples.
