Spectral studies of Pr3+ in different solvents

الملخص EN

Absorption spectra of Pr3+ ion in water (deionized), heavy water, dimethylsulphoxide, hexadeutrodimethylsulphxide, was studied in the UV-Vis.

and near IR regions.

Judd-Ofelt (T2, T4> T6), Slater-Condon (F2- F4- F6).

Racan (E\ E2, E3), and spin-orbit (£4 f) parameters of Pr3+ in the aforementioned media are evaluated.

The values of nephelauxetic ratio (B), Sinha's parameter (8%) and the bonding parameters (b1/2) are also discussed.
