Enhanced Eu3+ emission in aqueous phosphotungstate colloidal systems : stabilization of polyoxometalate nanostructures
Luminescent Eu(3+)-containing polyphosphate-tungstate aqueous colloidal systems were prepared and studied as a function of the relative polyphosphate-tungstate content. In polyphosphate-rich solutions, Eu(3+) ions occupy cagelike sites composed of phosphate groups from the metaphosphate chains. In t...
