Quantifying enhanced photoluminescence in mixed-lanthanide carboxylate polymers: sensitizationversusreduction of self-quenching

Author affiliations

Abstract

Remarkable enhancement and quenching of photo-luminescent emissions have been found in various mixed-lanthanide carboxylate polymers. In (Eu0.1:Tb99.9)2(2,2-biphenate)3(H2O)2 the Eu emission is comparable to the Eu homo-polymer, whilst the original Tb emission is reduced by ca. 80%. Either sensitized energy transfer or the reduction of self-quenching through dilution may play a dominant role.
