dc.description.abstract Thin films (1-3 μm thickness) of nanocomposites (NCs) based on organic compounds with Eu3+ ions (Eu(TTA)3H2O, Eu(TTA)3Phen, Eu(DBM)3Phen and Eu(TTA)2(Ph3PO)2NO3) and polymer polyvinylpyrrolidone (PVP) or copolymer styrenebutylmethacrilate in ratio of 1:1 (SBMA) were obtained by chemical methods and with different molar ratios into organic polymer matrix. NCs have been characterized by measurements of optical transmission and photoluminescence (PL). The PL of nanocomposites in all type of compounds with Eu3+ ions were detected the same spectra as specific for internal transitions 4f → 4f of the Eu3+ ion 5D0 → 7Fi (i = 0,1,2,3 and 4) centered at 537, 578, 615, 632,649, 690 and 705 nm, respectively at T=300 K. The dominant PL is in the position to 612 - 615 nm and the halfwidth is less than 10 nm and it is attributed to the transition 5D0 → 7F2. In nanocomposites, the effect of energy transfer from polymer matrix to coordinated molecule with subsequent transfer of them to Eu+3 ions have been identified. It was proposed some applications of given nanocomposites in optoelectronics and medicine. en_US
