dc.description.abstract | Electrolytes formed with poly(oxyethylene), POE, and europium picrate [Eu(pic)2(OH2)6]pic.6H2O (where pic denotes the picrate anion) or simply Eu(pic)3xH2O, have been represented by POEnEu(pic)3xH2O (where n represents the molar ratio of (OCH2CH2) units per Eu3+ ion). Materials with n ranging from 133 to 11 have been examined. A tentative attribution of the absorption bands of the mid-infrared spectra is presented. The spectral changes detected in the mid-infrared region and the modifications in the XRD patterns at increasing salt content show that PEOnEu(pic)3xH2O exerts an effective plasticizing role which leads to the complete supression of crystallinity at n = 11. The emission spectra of the complexes and their signature in the vC-O spectral region provide conclusive evidence that the Eu3+ ions are coordinated to the oxygen atoms of the polyether chains over the whole range of compositions studied. The photoluminescence spectra of the PEOnEu(pic)3xH2O electrolytes indicate that the Eu3+/ether oxygen complexation occurs with concomittant partial substitution of the water molecules from the cation coordination shell. The luminescence data obtained | por |
