Paper Abstract

The problem of obtaining low cost but efficient luminescent materials is still actually. Data concerning fabrication and luminescent properties of new composite materials on the base of thenoyltrifluoroacetone (TTA) of Europium(III) (Eu(TTA)3) and chalcogenide glasses doped with rare earth ions and polymers are presented. The visible emission spectra of the composites on the base of Eu(TTA)3 structured with phenantroline (Eu(TTA)3Phen) and copolymer from styrene and butylmethacrylate (1:1)(SBMA) under the excitation with N2-laser (λ=337 nm) contain sharp emission bands located at 354, 415, 580, 587, 590, 596, 611.4, 616.5, 621, 652, 690, 700, 713 nm. The nature of the observed emission bands and the possible mechanisms of the radiative electron transition in the investigated composite materials are discussed.
