Abstract
Optoelectronic property enhancement of poly(9,9 Prime -di-n-octylfluorenyl-2.7-diyl) (PFO) by different weight ratios of TiO{sub 2} nanoparticles (NPs) is demonstrated. The solution blending method was used to prepare the PFO/TiO{sub 2} nanocomposite. The microstructure of the composites was determined using X-ray diffraction while absorption and fluorescence spectra were recorded using UV-Vis and photoluminescence spectrophotometer respectively. X-ray diffractograms confirmed the formation of PFO/TiO{sub 2} nanocomposites. The absorbance and fluorescence spectra of the PFO/TiO{sub 2} nanocomposite were proportionately enhanced with the content of TiO{sub 2} NPs. The recombination between electrons of TiO{sub 2} and holes of PFO, through the interface of PFO/TiO{sub 2} nanocomposites enhanced the luminescence properties. Besides, the energy gap, line width of phonon emission intensity and vibronic spacing decreased. The line width of the energy gap tails, the vibronic transition intensity and the S-factor increased resulting from higher aggregation of films as supported by field emission scanning electron microscope images. The observed turn on voltage of the indium tin oxide/(PFO/TiO{sub 2})/Al organic light emitting diode device displayed a decreasing trend, suggesting an improvement on the performance of the device as the TiO{sub 2} content was increased. - Highlights: Black-Right-Pointing-Pointer No variation in structure of poly(9,9 Prime -di-n-octylfluorenyl-2.7-diyl) (PFO) and TiO{sub
