Abstract
Were obtained a new nanocomposite (NC) based on poly N-epoxy prolyl carbazol (PEPC) and the coordination compound luminophore Eu(o-MBA)3Phen, where o-MBA is o- methylbenzoic acid and Phen – phenanthroline. Nanocrystals of Eu(o-MBA)3Phen with the dimensions ~ 50 nm were uniformly incorporated into the PEPC polymer matrix with various concentrations. The absorption spectra of coordination compounds and thin layers of NC PEPC/Eu(o-MBA)3Phen revealed 1 intensive absorption bands at 2.02 eV. Photoluminescence (PL) spectra showed an intense red luminescence at 578 – 699 nm, which is assigned to the transitions 4D07Fi (i= 0,1,2 3 4) in the 4f-shell of the Eu3+ ion.
