Abstract
⺠The luminescence of Tb-doped silica nanoparticles is quenched in diluted solutions of FeCl3. ⺠This quenching arises from both dynamic and static mechanisms, the latter is predominant. ⺠Both aggregation of nanoparticles and ion exchange are the reasons of the quenching through static mechanism. ⺠The stripping of FeIII ions from silica surface by complex formation with anions reestablishes emission of Tb(III). ⺠The “off-on” switching of luminescence enables to recognize ATP in micromolar concentrations.
