The first optical sensor for Cu(II) detection, with upconverting luminescent nanoparticles as an excitation source, showing high selectivity and good linear Stern-Volmer characteristics, has been achieved through a fluorescence resonance energy transfer (FRET) process between NaYF4:Yb3+/Er3+ and RB-hydrazide. The sensing mechanism is then discussed.
