In this article, polycarbazole/tin oxide polymer nanocomposites were synthesized by an in-situ chemical polymerization of carbazole monomers using anhydrous iron (III) chloride as an oxidizing agent. The influence of SnO2 filler concentration on structural properties is investigated through X-ray diffraction, field emission electron scanning microscopy, energy-dispersive X-ray and Fourier transform infra-red spectroscopy. The optical studies were performed using UV–Vis absorption and fluorescence emission spectroscopy. X-ray diffraction spectrum reveals the formation of pure polycarbazole and incorporation of tin oxide nanoparticles into the polycarbazole matrix. EDX and FTIR spectra also confirm the formation of polymer nanocomposites. The change in morphological and nodular nature with the change in the weight percentage of SnO2 is noticed from FESEM. UV–Vis absorption spectra reveal the red shift of π—π* transition of polycarbazole due to the incorporation of tin oxide into the polymer chain. From photoluminescence spectra, we have observed that fluorescence emission intensity and wavelength varies with different weight percentage of SnO2 nanoparticles.
