dc.description.abstract	Coordination compound tris(thenoyltrifluoroacetonato)bis(triphenylphosphine oxide) europium(III) Eu(TTA)3(Ph3PO)2, where TTA is the thenoyltrifluoroacetonate monoanion (C8H5F3O2S), Ph3PO is triphenylphosphinoxide (TPPO), is synthesized. Solutions with different molar ratios of Eu(TTA)3(Ph3PO)2 and thin film samples is characterized by optical transmission and photoluminescence (PL) spectroscopy. The displacement of the absorption threshold to infrared is observed with increasing coordination material concentration in solutions. PL emission at T = 300 K in the solutions and the bulk material is detected as specific bands of the internal transitions in the 4f shell of the Eu3+ ion 5D0 → 7 Fi (i = 0,1,2,3 and 4) centered at 537, 578, 615, 650, and 702 nm. The dominant PL band is positioned at 615 nm with the FWHM less than 10 nm, and this band is attributed to the transition 5D0 → 7 F2.	en_US
