An intelligent copper(II) luminescent sensor using europium narrow emissions based on titania hybrid material

Abstract A new kind of europium 2,6-Pyridinedicarboxylic acid complex was synthesized and immobilized in titania via modification of this network. Then a europium luminescent hybrid material was fabricated, which gave prominent red emission. More importantly, this target material exhibited highly selective and rapid quenching effect to copper ion in contrast with Ca2+, Na+, K+, Ni2+, Zn2+, Mn2+, Ag+ and Fe3+ in pure water. The europium containing titania hybrid material could be promising for the fabrication of functional sensing devices.
