Europium(III) coordination compound Eu(TTA)3(Ph3PO)2 (1) {TTA = thenoyltrifluoroacetonate, Ph3PO = triphenylphosphine oxide} has been prepared and characterized. Powder samples of the complex have been characterized by thermogarvimetric analysis (TGA), optical transmission and photoluminescence (PL) spectroscopy. PL have been registered for different temperatures in the range 11-300 K. The PL spectra was detected as specific narrow emission bands of internal transitions 4f→4f of the Eu3+ ion 5D0→7Fj (j = 0-4). The major bands are centered at ca 580, 595, 615, 650 and 698 nm. PL data can be interpreted in the framework of the mechanism of energy transfer from the organic ligand matrix to Eu3+ ion. |
