Sensitized luminescence from novel pyrazolone based β-diketonate complexes of Eu3+
Journal Title: Bulletin of Pure and Applied Sciences Sec. C – Chemistry - Year 2018, Vol 37, Issue 1
Abstract
New pyrazolone based fluorinated ligand, 3–methyl 4–(2,2,3,3,3–penta fluoro–1–hydroxypropylidene)–1–phenyl–1H–pyrazol–5(4H)–one has been synthesized and well characterized. Europium–containing complexes were synthesized by adduct formation between 3–methyl 4–(2, 2, 3, 3, 3-penta fluoro–1–hydroxypropylidene)–1–phenyl–1H–pyrazol–5(4H)–one and europium (III) complex and a bidentate neutral donor 1,10–phenanthroline (phen). The emission spectra of the complexes display characteristic sharp peaks in the 575–700 nm region associated with the 5D07FJ (J = 0–4) transitions of the Eu3+ ion.
