Description
Summary:Yttrium is stoichiometrically doped into europium by mole percentage, during the synthesis of Y sub((1-x))Eu sub((x))(TTA) sub(3)(Phen), using solution techniques (where x=0.2, 0.4, 0.5, 0.6 and 0.8, TTA=thenoyltrifluoroacetone and Phen=1,10-phenanthroline).These complexes were characterized using different techniques such as X-ray diffraction, thermogravimetric/differential thermal analysis, optical absorption and emission spectra. Thin films of the doped Eu-Y complexes were prepared on a glass substrate under a high vacuum of 10 super(-6) Torr. The photoluminescence spectra of these thin films were recorded by exciting the sample at a wavelength of 360 nm. The emission peak for all the synthesized complexes centered at 611 nm; maximum emission intensity was obtained from Y sub(0.6)Eu sub(0.4) (TTA) sub(3)(Phen). The results proved that these doped complexes are more economical than pure Eu(TTA) sub(3)(Phen) and are best suited as red emissive material for energy-efficient and eco-friendly organic light-emitting diodes and displays.
