摘 要：A novel covalently bonded Eu3+-based silica hybrid material was designed and its spectrophotometric anion sensing property was studied. The fluorescent receptor（europium complex） was covalently grafted to the silica matrix via a sol-gel approach. FTIR, UV-vis spectra, scanning electron microscopy（SEM）, transmission electron microscopy（TEM）, X-ray diffraction（XRD） and photoluminescent spectra were characterized, and the results revealed that the hybrid material with nanosphere structure displayed excellent photophysical property. In addition, the selective anion sensing property of the hybrid material was studied by UV-vis and fluorescence spectra. The results showed that the hybrid material exhibited a smart response with fluoride anions.
