N2 - The luminescent coarse-, micro-and nanocrystalline europium(III) terephthalate tetrahy-drate (Eu2bdc3‧4H2O) metal-organic frameworks were synthesized by the ultrasound-assisted wet-chemical method. Electron micrographs show that the europium(III) terephthalate microparticles are 7 μm long leaf-like plates. According to the dynamic light scattering technique, the average size of the Eu2bdc3‧4H2O nanoparticles is equal to about 8 ± 2 nm. Thereby, the reported Eu2bdc3‧4H2O nanoparticles are the smallest nanosized rare-earth-based MOF crystals, to the best of our knowledge. The synthesized materials demonstrate red emission due to the5D0–7FJ transitions of Eu3+ upon 250 nm excitation into1ππ* state of the terephthalate ion. Size reduction results in broad-ened emission bands, an increase in the non-radiative rate constants and a decrease in both the quantum efficiency of the5D0 level and Eu3+ and the luminescence quantum yields. Cu2+, Cr3+, and Fe3+ ions efficiently and selectively quench the luminescence of nanocrystalline europium(III) ter-ephthalate, which makes it a prospective material for luminescent probes to monitor these ions in waste and drinking water.
