Abstract: The luminescence of Eu²⁺ in Ba₂CaB₆O₁₂ has been investigated under vacuum ultraviolet and ultraviolet excitation. Two different crystallographic sites are available for Eu2+ in Ba₂CaB₆O₁₂. In this structure, there are linear rows of three cations in the order of Ba²⁺, Ca²⁺ and Ba²⁺, Ca²⁺ being in the central position. The emission spectra of Eu²⁺ under vacuum ultraviolet and ultraviolet consist of two broad bands peaking at 445 and 465 nm, which are associated with the fd transitions of Eu²⁺ in the sites of Ba²⁺ and Ca²⁺, respectively. Two weak peaks in vacuum ultraviolet range are observed at 160 nm and 200 nm.
