Abstract
We report a new type of remote optical sensor of metal ions in solutio n based on fluorescence lifetime quenching due to dipole-dipole energy transfer across a polymer-water interface. Ion selectivity is provide d by spectral overlap between the sensor fluorescence and metal ion ab sorption. The sensor is demonstrated in the detection of cobalt ions i n water at levels down to 17 mu g.
