Luminescence Study of the Samarium(II) Sites in Samarium: Barium Octaborate as Differentiated by Excitation Wavelength and Temperature. | LitMetric

AI Article Synopsis

  • The study focuses on the properties of divalent samarium in a barium octaborate matrix using emission spectroscopy.
  • One samarium site shows a significant temperature sensitivity when excited at 532 nm, enabling the differentiation between two main Sm(II) sites within the compound.
  • The symmetry of the first samarium environment is likely C or C, while the second site shows a different symmetry of C.

Article Abstract

Divalent samarium incorporated in a barium octaborate matrix prepared by firing homogeneous precipitates has been studied with emission spectroscopy. One of the samarium sites associated with this product exhibits an extremely strong temperature dependence upon using an excitation wavelength of 532 nm. This effect allows for specific differentiation between the two major Sm(II) sites associated with this compound. Based on the assignment of the emission features to specific sites, the symmetry of the first samarium environment is thought to be C or C while that associated with the second site appears to be C.
