Characterization the nanocomposites of coordination compounds of Eu3+ ions/PEPC by TGA, DSC, TEM AND SEM

Abstract

Coordination compounds of Europium(III) are excellent materials for a new generation of light emitting devices with high efficiency, easy color tuning, temperature insensitivity, and high stability. Compounds Eu(TTA)3(Ph3PO)2, Eu(DBM)3Phen and Eu(o-MBA)3Phen and polymer nanocomposites (NCs) on their base were obtained. For coordonation of Eu3+ as active ligands were used TTA (thenoyltrifluoroacetonato (C8H5F3O2S)), DBM (dibenzoylmethane)and o-MBA – omethyl benzoate and as neutral ligands Ph3PO (triphenyl phosphine oxide) and Phen (1,10-phenanthroline). As polymer PEPC (poly-N-epoxypropyl carbazole) was used.
