A FRET based fluorescent probe (RDENAPH) containing a 2-hydroxynaphthalene unit as a donor and rhodamine B as an acceptor can discriminate Cr3+ and Fe3+ from other common metal ions through ratiometric sensing. The FRET process has been established from absorption, emission and lifetime decay studies. The probe can stain intracellular Cr3+ and Fe3+ in contaminated living cells.
