The absorption spectra of a EuCl3.H2O solution was measured and absorption cross-section of Eu3+ was estimated. The observed overlap predicts a resonant energy transfer from Tetracycline to Eu3+. The microscopic parameter of energy transfer was obtained using the overlap integral calculation considering a dipole–dipole energy transfer mechanism and results were compared considering an energy transfer by exchange. In this work, we report also the optical properties of Tc–Eu complex when urea hydrogen peroxide is added to the aqueous solution.p. 288-290openAccessabsorption spectraaqueous solutionsdipolesenergy transfereuropium chlorideseuropium ionseuropiumglucosehydrogen peroxideligandsoptical propertiestetracyclinesureaArtigo de periódico122-12310.1016/j.jlumin.2006.01.143https://orcid.org/0000-0003-0092-9357
