Abstract

NaSrR(BO₃)₂ (R = Ho-Lu, Y, Sc) compounds were obtained for the first time. Their structures exhibit disordered positions of Sr²⁺ and Na⁺ atoms while RO₆ polyhedra are connected through the BO₃ groups. Large distances between R atoms and high transparency in the range of 250-900 nm make them promising for phosphor applications. A pathway to obtain single crystals was shown by growing NaSrY(BO₃)₂ and NaSrYb(BO₃)₂ by the top seeded solution growth method with Na₂O-B₂O₃-NaF flux.
