Abstract

An increase in the europium emission band was observed, for the first time, with addition of urea hydrogen peroxide to the tetracycline-europium (Tc-Eu)solution. We have observed that the wavelength, the band width and the area of 5D0-->7F2 europium transition change with the urea hydrogen peroxide concentration. We claim that the tetracycline-europium complexes can be used as probes of urea hydrogen peroxide concentration.
