Fluorescence Quenching of Europium(III) by the Interaction with Copper(II) or Nickel(II) Complex of <i>N</i>,<i>N</i>′-Disalicylidene-1,3-propanediamine

Abstract

Abstract Effect of the co-existence of the titled copper(II) or nickel(II) complex upon the fluorescence of europium(II) has been investigated in methanol. Intensities of the fluorescent bands at 580, 593, 618, 687, and 696 nm are significantly quenched by the addition of the copper(II) or nickel(II) complex but not by a simple metal salt, copper(II) nitrate trihydrate or nickel(II) nitrate hexahydrate.
