Effect of Co-doped alkali earth metal Ca2+, Mg2+, Sr2+ ions on spectral parameter for rare earth, Pr(III)-2-Amino Benzothiazole doped system in micellar medium

Abstract

Electronic transition levels of Pr(III) lanthanide ion with aromatic heterocyclic ligand containing N,S,O atom i.e. Pr(III)-2AB system/complex have been determined by electronic spectra in micellar (TX-100) medium at 25°. Using the Gaussian curve, the half band (υ_1/2) width, and energy expression have been determined, such as Taylor’s series expansion is utilized to express the energy of the j^th level. The interactions between lanthanide (III) ion and ligand have been evaluated in terms of Slater-Condon (F_K), Lande (E^K), Racah (ζ_4f) parameters and bonding parameters. Four assignments ³H₄→³P₂, ³H₄→³P₁, ³H₄→³P₀ and ³H₄→¹D₂ were made to justify these interaction parameters. In this research paper we have explored theoretical as well as practical analysis of electronic spectra of Pr(III) ion in micellar medium. The results of interaction parameters have been obtained as F₂=307.10, F₄=76.12, F₆=6.78, E₁=4508.84, E₂=23.58, E₃ =455.88 and ζ_4f =761.29.
