Barbosa A, Maia L, Montanari B, Goncalves R, Messaddeq Y, Ferreira R, et al.
Langmuir . 2010 Aug; 26(17):14170-6. PMID: 20684653
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...
