Synthesis and Characterization of New Photoluminescent Material Tris (2-Methyl 8-Hydroxy Quinoline) Europium Eu(mq)3

A new photoluminescence material, namely tris (2-methyl 8-hydroxy quinoline) europium Eu(mq)₃ has been synthesized and characterized by different techniques. The prepared material Eu(mq)₃ was characterized for structural, thermal and photoluminescence analysis. Structural analysis of this material was done by fourier transformed infrared spectroscopy (FTIR) and mass spectroscopy. Thermal analysis of this material was done by thermal gravimetric analysis (TGA) which shows thermal stability up to 230°C. Absorption and emission spectra of the material was measured by UV-visible spectroscopy and photoluminescence spectroscopy. Solution of this material in ethanol showed absorption maxima at 300nm which may be attributed due to (π - π^*) transitions. The photoluminescence spectrum of Eu(mq)₃ in ethanol showed most intense peak at 430 nm. The time resolved photoluminescence spectra of this material Eu(mq)₃ showed one life time component which was 1.4ns.
