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

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 Ca 2+ , Na + , K + , Ni 2+ , Zn 2+ , Mn 2+ , Ag + and Fe 3+ in pure water. The europium containing titania hybrid material could be promising for the fabrication of functional sensing devices.
