NaSrR(BO 3 ) 2 (R = Ho-Lu, Y, Sc) compounds were obtained for the first time. Their structures exhibit disordered positions of Sr 2+ and Na + atoms while RO 6 polyhedra are connected through the BO 3 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(BO 3 ) 2 and NaSrYb(BO 3 ) 2 by the top seeded solution growth method with Na 2 O-B 2 O 3 -NaF flux.
