Description
Optical absorption spectra of Eu(TTA)3Phen (TTA: Thenoyl Trifluro Acetone) and EuxRe(1-x)(TTA)3Phen (where Re = Y, Tb) organic luminescent complexes in different organic solvents are measured to study the shift of the π → π* and the n → π* optical transitions due to Eu3+ ion and β-diketonate moieties. All complexes show good solubility in different basic and acidic solvents. Two optical absorption peaks observed in the UV region of the spectra of solvated complexes shift when the solvent is changed. With a variation in the solvent from basic to acidic, staggering differences in optical absorptions are noticed. Absorption peaks shift bathochromically by a few nm as the solvent varies from basic to acidic. The optical energy band gaps of EuxRe(1-x)(TTA)3Phen are very similar for all the solvents used. A substantial dependence of the electronic absorption spectra of Eu complexes on the solvent is reported.
