摘要

We report preparation and characterization of new nanocomposite material based on oligomers poly-N-propyl carbazole (PEPC) and the organic compound Eu(o-MBA)(3)Phen, where o-MBA ortho-methylbenzoic acid, Phen phenanthroline. Nanocrystals Eu(o-MBA)(3)Phen with dimensions 20-50 nm have been incorporated into the polymer matrix PEPC with concentrations 5.78%, 2.73%, and 1.30%. Optical absorption thresholds are located in the range 3.34-3.40 eV in dependence on the concentration of Eu(o-MBA)(3)Phen compound. The photoluminescence spectra show a number of strong emmission bands, which are associated with the transitions D-4(0)-> F-7(1) (i = 0,1,2,3,4) in the 4f shell of the Eu3+ ion. Examination of the photoluminescence spectra of luminophore organic compound Eu(o-MBA)3Phen and nanocomposite PEPC/Eu(o-MBA)(3)Phen demonstrates the enhancement of the photoluminescence emission in PEPC/Eu(o-MBA)3Phen compared with Eu(o-MBA)(3)Phen
