Abstract

Poly(9,9′-dioctyl fluorene) was used as an emitting material in the light-emitting diodes. After annealing at a high temperature, such as 100 °C, the device shows higher performance than the controlled device. This may be attributed to the surface structures and polymer morphology. UV-vis and photoluminescence spectra were used to study the phase and photophysical characteristics. Also, reflection-absorption Fourier-transform infrared spectroscopy (RA-FTIR) has been performed on the samples to investigate how the device performance was influenced.
