Abstract
The reduction of samarium in air fired samples of barium tetraborate has been identified for the first time by divalent samarium emission spectroscopy. The samarium(II) fluorescence is significantly quenched at ambient temperatures, but is apparent upon cooling of the sample to 77 K. Formation of the divalent samarium in the system is limited to short firing times and a small range of firing temperatures from 825 to 900 °C. The formation of a more luminescent pentaborate impurity phase is often seen in the barium tetraborate system, even with stoichiometric preparation of the barium tetraborate.
