A new probe (Z)-3-((naphthalen-1-ylmethylene)amino)phenol has been synthesized by condensation reaction between 1-naphthaldehyde and 3-aminophenol for the fluorescent sensing of Ce3+ by "on" mode and dichromate (Cr2O72-) by "off" mode. Metal ions-Ag+, Al3+, As3+, Ba2+, Ca2+, Cd2+, Ce4+, Co2+, Cr3+, Cr6+, Cu2+, Fe2+, Fe3+, Hg2+, K+, La+, Li+, Mg2+, Mn2+, Na+, Ni2+, Pb2+, Zn2+and anions Br-, C2O42-, CH3COO-, Cl-, CO32-, F-, H2PO4-, HCO3-, HF2-, HPO42-, I-, MnO4-, NO3-, OH-, S2-, S2O32-, SCN-, SO42- do not interfere. The limit of detection (LOD) for sensing Ce3+ and Cr2O72- ions are 1.286 × 10-7 M and 6.425 × 10-6 M, respectively.
