The sensing of phosphate anion (PO43-) is an important subject for human health and environmental monitoring. Herein, a unique ratiometric fluorescent nanoprobe based on postsynthetic modification of metal-organic frameworks (MOF) UiO-66-(COOH)2 with Eu3+ and Ce3+ ions toward PO43- was proposed (designated as Eu/Ce/Uio-66-(COOH)2). The Eu/Ce/Uio-66-(COOH)2 nanoprobe exhibits three emission peaks at 377 nm, 509 nm, and 621 nm with the single excitation wavelength at 250 nm, respectively. The strong coordinating interaction between Ce3
