Description :
Colour purity of lanthanide complexes is tough criteria for red emission display devices. Synthesis of Eu3+( TTA)3 Phen (TTA: Thenoyl Trifluro Aceton) and its blended thin films with polymethyl methacrylate (PMMA) for red emission is reported here. Stability of Eu3+( TTA)3 Phen against Eu3+( TTA)3 is discussed in this paper. Fourier transform infrared spectroscopy (FTIR) analysis and Photoluminescence property of Eu3+( TTA)3 Phen and blended thin film of Eu3+( TTA)3 phen introduced in polymethyl methacrylate(PMMA) is studied at room temperature and compared. At room temperature, composition of typical Eu3+ ion red emission obtained from synthesized composite Eu -complex . Photoluminescence emission line of pure Eu3+( TTA)3 Phen and Eu3+( TTA)3 Phen /PMMA obtained at 612 nm due to 5D0→7F2 electric –dipole transition. Absorption peak in near UV region is the interest of using this complex for PLLCD application.
