摘要: Abstract A europium (III) complex containing 1,5-styrylacetylacetone ligands, Eu(DSACAC)3Phen was synthesized. Its photoluminescence properties have been investigated by fluorescence emission spectra and lifetime measurements. According to the spectra, Judd–Ofelt parameters Ω2, Ω4 of calculated radiative were presented also. It showed that increase conjugation length in DSACAC ligand can also improve metastable state τm, luminescence quantum yield η stimulated cross-section σ 5D0 → 7F2 transition.
