In this work we investigate the europium optical properties of three tetracyclines europium complexes: Metacycline (MTc), Oxytetracycline (OTc), and Chlortetracycline (CTc), in the presence and absence of hydrogen peroxide (HP). The results show that the emission band of EuOTc have enhancement in the presence of hydrogen peroxide. A calibration curve was shown for this complex with the best molar ratio obtained.715-721openAccesshydrogen peroxideeuropium complexesrare earth complexesoptical propertiesfluorescencespectroscopyArtigo de periódico41910.1007/s10895-009-0465-zhttps://orcid.org/0000-0003-0092-9357
