Nanocomposites (NCs) thin films based on oligomer poly-N-epoxypropylcarbazole (PEPC) and organic coordinated compounds (OCC) have been obtained by chemical methods. Absorption threshold for samples with different concentrations was determined as 3.34 - 3.4 eV. Photoluminescence spectra reveal a number of emission bands centered at 580, 590, 612-615, 651, and 700 nm, which can be associated to internal 4f - 4f transitions of Eu3+ ion 5D0 → 7Fi (i = 0,1,2,3 and 4). By comparing the photoluminescence spectra of the organic compound and of the PEPC/Eu(o-MBA)3Phen nanocomposite one can observe the amplification of the photoluminescence intensity in NC. |
