文摘Exploration of ultraviolet phosphates with balanced overall performance is of great significance and difficulty.Herein,the first barium bismuth zincophosphate,Ba_(2)Bi_(2)[Zn(PO_(4))_(4)],was rationally obtained by ion mixing and anionic condensation,while single crystals of Ba_(2)Bi_(2)[Zn(PO_(4))_(4)]were synthesized by a high temperature molten salt method.In the strucutre of Ba_(2)Bi_(2)[Zn(PO_(4))_(4)],unprecedented_(∞)[Zn(PO_(4))_(4)]^(10−)chains,which were made up through the condensation of infrequent[Zn(PO_(4))_(5)]^(13−)groups,were ionically bridged by massive Ba^(2+)and Bi^(3+).Having benefitted from its unique one-dimensional anionic frame and the ultilization of mutiple ions,Ba_(2)Bi_(2)[Zn(PO_(4))_(4)]was characterized by a balanced overall performance over birefrigence,band gap and physicochemical stability.Especially,Ba_(2)Bi_(2)[Zn(PO_(4))_(4)]was verified as a congruently melting crystal with a high melting point of about 965℃,being conducive to practical applications.
