In this review, recently discovered phosphate materials containing different anionic groups, i.e., isolated [PO4], [P2O7] dimer, [P3O（10）] trimer, and [PO3]∞ chain, are summarized, including their syntheses, structures, NLO performances and properties. Especially phosphates with short absorption edges in the deep-UV region and good SHG efficiency are introduced in detail. We hope that this work will present a clear view of the crystal chemistry of phosphates and promote the discovery of new high-performing second-order NLO materials to meet the urgent needs in laser science.展开更多
