摘 要：Fluorescent microspheres of polystyrene-based Eu（Ⅲ） complexes were prepared from TentaGel resin,2,6-bisbenzimidazolylpyri-dine and europium nitrate. The microspheres were characterized by FTIR spectroscopy, elemental analysis, XPS measurements and fluores-cence spectroscopy. Characteristic red emission under irradiation of365nm light from a hand-held UV lamp was observed for the micro-spheres either in a solution or solid-state.Fluorescent quenching was observed when the microspheres were exposed to a trace amount of di-ethyl chlorophosphate （DCP）in the dispersion. The material and property can be potentially used to fabricate chemosensor in the detection of organophosphates.
