Abstract

A new Eu(III)-doped polyoxotitanate (POT) cage [Ti₂O(OEt)₈(EtOH)EuCl]₂ can be used as a single-source precursor for the formation of nanostructured Eu-containing titania composites and flexible fluorescent films, which exhibit significant red luminescence and are attractive fluorescent materials.
