Abstract

An aqueous room-temperature phosphorescent (RTP) probe for Gd³⁺ is reported based on Gd³⁺-induced intersystem promoting effect and the oxygen-shielding property of the Gd³⁺/AMP/fluorescein coordination polymer nanoparticles (CPNs). Besides selective Gd³⁺ detection, the results are important for harnessing the advantages of RTP detection in an aerated aqueous solution, which is difficult with current phosphors.
