磷酸盐是另一类正在探索的深紫外非线性光学材料。作为一种材料，组成越简单，合成和应用越有利。采用高温固相法合成了一种简单的碱土金属磷酸盐β-Ba（PO 3）2。值得一提的是，它在磷酸盐中具有较短的截止边（<190 nm）和相对较大的双折射（Δn = 0.032@1064 nm），并且通过优化碱性阴离子的排列可以增强光学各向异性和双折射。结合理论分析，进一步阐述了结构与性能的关系。此外，还研究了β-Ba（PO 3）2的热学性质、线性光学和非线性光学性质。
Phosphates are another new family of exploring deep-ultraviolet nonlinear optical materials. As one material, the simpler the composition is the more favorable synthesis and application is. In this work, a simple alkaline earth metal phosphateβ-Ba(PO3)2was synthesized by high temperature solid phase method. It is worth mentioning that it has short cut-off edge (<190 nm) and relatively large birefringence (Δn = 0.032 @ 1064 nm) in phosphates and the optical anisotropy and birefringence can be enhanced by optimizing the basic anion arrangement. Combining with theoretical analysis, the relationship between structure and performance is further elaborated. In additional, thermal properties, linear optical and nonlinear optical properties forβ-Ba(PO3)2were also investigated.
