| 英文摘要 | LiB3O5 and CsB3O5 are two excellent nonlinear optical borate crystals containing B3O7 groups. With a difference of aikali metal ions in structure, LiB3O5 and CsB(3)O(5)exhibit different crystallization habits respectively. The former is an incongruent compound, which cannot crystallize from its melt; however, the latter is a congruent compound obtained by cooling its melt directly. In this work, using Raman spectroscopy and ab initio calculation, structures of LiB3O5 and CsB3O5 melts were investigated, and then the influence of alkali metal ions on melt structures was discussed, finally, the relationship between crystallization habits of LiB3O5 and CsB3O5 and their melts was proposed. Our results suggested that boron oxide species of LiB3O5 and CsB3O5 melts were in the form of six-membered rings B3O7 and B3O6O represents a bridging oxygen); Raman frequency of the symmetric breathing vibration of six-membered rings shifted to low frequency with the addition of BO4 tetrahedrons in rings; the relatively large amount of BO4 tetrahedrons was found in LiB3O5 melts; however, Cs+ ions with larger ion radius hindered formation of BO4 tetrahedrons, and then reduced the BO4/BO3 ratio of the melt. Finally, considering the growth mechanism of LiB3O5 and CsB3O5 crystals (Wang D, Wan S M et al. 2011 CrystEngComm 13 5239), we propose that the amount of BO4 tetrahedrons in melts, which is influenced by aikali metal ions, determines LiB(3)O(5)and CsB3O5 crystallization habits, therefore, and suggest the reduction of O-4 tetrahedrons in melts is an effective way to crystallize LiB3O5. |
