The monodisperse and water‐soluble YVO 4 :Eu nanoparticles (NPs) with uniform size and shape were synthesized by a facile and environmentally friendly co‐precipitation at room temperature with poly(acrylic acid) (PAA) as surfactant and water as solvent. The morphology of the obtained YVO 4 :Eu NPs is sphere‐like with a diameter of about 38 nm. Intense red emission from NPs is achieved under ultraviolet (UV) excitation. The intense red emission could be selectively quenched by Cu 2+ ions with limit of detection (LOD) as low as 0.57 μM in aqueous solution. The emission quenched by Cu 2+ ions would be recovered when adding ethylenediamine tetraacetic acid (EDTA), due to the strong interaction between Cu 2+ ions and EDTA. These results indicate that the NPs would be a potential sensor for detecting Cu 2+ ions in aqueous solution.
