Abstract

Polymeric thin films of poly (N-vinylcarbazole) (PVK) with titanium oxide (TiO) were fabricated by using spin 2 coating technique. The X-ray diffraction (XRD) data revealed the amorphous nature of PVK polymer matrix and increased with increase of TiO concentration. The complexation of the polymer was confirmed by Fourier transform 2 infrared (FTIR) and UV-Visible studies. The Electroluminescence (EL) spectra of the thin films of polyvinylcarbazole (PVK) with titanium oxide (TiO) showed an enhancement in the electroluminescence properties with various molar 2 concentration of dopant. Moreover, the TiO based Poly (N-vinylcarbazole) (PVK) exhibited a remarkable variation at 2 higher molar concentration of the EL spectrum as compared to that of the pure polyvinylcarbazole film. The current voltage characteristics of the various molar concentrations of TiO shows the same trained in comparison with EL.

Keywords: Electroluminescence (EL), Poly (N-vinylcarbazole) (PVK)
