Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book describes Opto-electronic properties of three new carbazole based co-polymers that can be implemented as host in phosphorescence polymer light-emitting diode. We present absorption, steady-state emission and time resolved emission spectroscopy of carbazole based conjugated polymers. The decay kinetics of triplet emission of the co-polymers was observed after optical excitation. Several findings such as optical band-gap, singlet to singlet transition energies, triplet to triplet transition energies, exchange energies ( EST), Stoke's shift have been presented. The onset of absorption is at 3.10-3.25 eV for P1, P2 and P3 polymers respectively. One emission band originating from singlet excited state is observed at RT. The gaps between singlet and triplet excited states are 0.44-0.47 eV. From decay kinetics the triplet excited state life-times were found to be several orders of ms at 10-13 K that reduces to less than 3 ms at room temperature. At room temperature delayed fluorescence has been observed for all three polymers. An energy band diagram including lower lying excited states has been constructed and compared. 108 pp. Englisch. …
