Ultra-selective detection of radionuclide Sr<sup>2+</sup><i>via</i> tuning valence Eu<sup>3+</sup> to Eu<sup>2+</sup> in lanthanide clusters
A europium-nickel nanocluster probe (Eu-NiCs) was engineered <i>via</i> valence-programmable synthesis for selective Sr<sup>2+</sup> detection. This one-step hydrothermal design achieves unmatched selectivity (Sr<sup>2+</sup>/Ba<sup>2+</sup> = 14.7) and a 2.1 μg g<sup>-1</sup> detection limit.
