Na3AEZn2B3O9 (AE = Mg, Ca): two new short-wave ultraviolet beryllium-free Sr2Be2B2O7-type zincoborates designed by chemical cosubstitution

With reference to Sr 2 Be 2 B 2 O 7 , two new short-wave ultraviolet beryllium-free Sr 2 Be 2 B 2 O 7 -type zincoborates, Na 3 AEZn 2 B 3 O 9 (AE = Mg and Ca), were successfully designed by a cosubstitution strategy and synthesized by a molten-salt method.
