In our work we obtained the white light emitting material by copolymerization of vinylcarbazole with uinylimidazole. The ratio of vinylcarbazole to vinylimidazole comers in the obtained copolymer (PVKI) was 4:3. This article is concerned with OF the photoluminescence (PL) study of PVKI thin films deposited on the glass substrate by the dip-coating method. The obtained results were compared with the photoluminescence of thin films of poly (N-vinylcarbazole) (PVK) and poly (N-vinylimidazole) (PVI) deposited by the same technique. All PL spectra have been measured under steady state excitation (lambda = 325 nm) in the temperature range from 13 K to 325K.
