Hybridization-activated new deep ultraviolet transparent nonlinear optical material Ba-11[Al(PO4)(4)](P2O7)(PO4)(3) with balanced overall performance and parsimony-forbidden structure

摘要

A new nonlinear optical material, Ba-11[Al(PO4)(4)](P2O7)(PO4)(3), was rationally synthesized via the hybridization of three types of anionic groups, namely [AlO4](5-), [PO4](3-) and [P2O7](4-), via a spontaneous nucleation method. Ba-11[Al(PO4)(4)](P2O7)(PO4)(3) was characterized with high thermal stability, deep ultraviolet transparency and moderate second-order optical nonlinearity, which were favourable for practical applications.
