- We present the results concerning the excitation and emissions spectra of poly(N-carbazole) (PVK) blended with poly(vinylidene fluoride-co-hexafluoropropene), (PVDF-HfP) and polyvinylpyrrolidone (PVP). Thin films of PVK blended with PVDF-HfP (PVK:PVDF-HfP) and PVP (PVK:PVP) were prepared using doctor blade technique on spectrosil substrate. The influences of polymer blends to the excitation and emission spectra were observed under UV excitation source of a xenon lamp. The result shows a discrepancy in the maximum excitation and emission for each samples. The possible energy transfer and recombination mechanisms have been related with singlet-singlet semi-empirical INDO electronic calculation and FTIR measurements.
