Synthesis and Photoluminescence Property of Eu3+ (Tta)3 Phen and Its Blended Thin Films Embedded in Pmma for Optoelectronic PLLCD Application

Colour purity of lanthanide complexes is tough criteria for red emission display devices.Synthesis of Eu 3+ ( TTA)3 Phen (TTA: Thenoyl Trifluro Aceton) and its blended thin films with polymethyl methacrylate (PMMA) for red emission is reported here.Stability of Eu 3+ ( TTA)3 Phen against Eu 3+ ( TTA)3 is discussed in this paper.Fourier transform infrared spectroscopy (FTIR) analysis and Photoluminescence property of Eu 3+ ( TTA)3 Phen and blended thin film of Eu 3+ ( TTA)3 phen introduced in polymethyl methacrylate(PMMA) is studied at room temperature and compared.At room temperature, composition of typical Eu 3+ ion red emission obtained from synthesized composite Eu -complex .Photoluminescence emission line of pure Eu 3+ ( TTA)3 Phen and Eu 3+ ( TTA)3 Phen /PMMA obtained at 612 nm due to 5 D0→ 7 F2 electric -dipole transition.Absorption peak in near UV region is the interest of using this complex for PLLCD application.
