Hybridization-activated new deep ultraviolet transparent nonlinear optical material Ba11[Al(PO4)4](P2O7)(PO4)3 with balanced overall performance and parsimony-forbidden structure

A new nonlinear optical material, Ba11[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. Ba11[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.
