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.
首次观察到，向四环素 - 铕（Tc - Eu）溶液中添加尿素过氧化氢后，铕发射带有所增加。我们观察到，5D0→7F2铕跃迁的波长、带宽和面积会随尿素过氧化氢浓度的变化而改变。我们认为，四环素 - 铕配合物可作为尿素过氧化氢浓度的探针。
