Temperature dependence of the intensity of fluorescence of poly(n-vinylcarbazole) films

  • Published:
Polymer Bulletin Aims and scope Submit manuscript

Summary

The fluorescence spectra of thin films of poly(N-vinylcarbazole), PVCA, were measured at temperatures between 103 K and 535 K by constant excitation light intensity. Below 300 K, the corrected spectra were divided into bands belonging to different emitting species of PVCA. Temperature changes of the intensity of fluorescence of the two main excitation energy traps in PVCA are discussed using the simplified kinetic model of Johnson. Local anomalies on the curves of intensity of excimer fluorescence versus temperature measured at constant wavelength reflex the γ- and δ- relaxation regions in PVCA.
