Computational and characterization studies of non- conjugated poly (N-vinylcarbazole) blends as host polymer for phosphorescence emission / Ahmad Nazib Alias
Polarized absorption, optical dielectric spectra, absorption excitation and emissions spectra of blended poly (N-carbazole) (PVK) with poly(vinylidene fluoride-co-hexafluoropropene) (PVDFHFP) and polyvinylpyrrolidone (PVP) in the same composition have been investigated. The electronic structure has...
