Abstract

Plasma-polymerized 1-benzyl-2-methylimidazole (PPBMI) thin films have been deposited onto glass substrates by glow discharge technique. Scanning electron micrographs reveal that the surface morphology of PPBMI thin films is uniform and flawless. Fourier transform infrared spectroscopy analysis shows that the chemical composition of PPBMI films is different from that of the BMI. From the ultraviolet-visible spectra direct and indirect transition energy gaps were determined to be between 3.10 and 3.35 eV and 1.80 and 1.95 eV, respectively, for as-deposited PPBMI thin films of different thicknesses. Both direct and indirect transition energy gaps increase with increasing thickness and decrease upon heat treatment.
