摘要

将碱土金属钡引入焦磷酸盐，通过高温固相法合成了一种新的非线性光学材料Ba_2P_2O7，该化合物结晶于■m(No.189)非中心空间群，其三维网状结构中，P_2O7基团按照ABAB方式形成不同朝向的P_2O7二聚体簇；钡原子与氧原子配位形成Ba O10和Ba O11多面体．研究结果表明：该晶体具有短的紫外截止边(195 nm)及良好的热稳定性，同时讨论了二阶倍频效应与阴离子基团排布之间的关系．第一性原理计算证明了该化合物的光学性能主要决定于P-O基团．

Abstract

In this study

the alkaline earth metal Ba was introduced into pyrophosphates and a new nonlinear optical material Ba_2P_2O7 was synthesized by high temperature solid-state method.The compound crystallized in ■m(No.189) noncentrosymmetric space group.In its three-dimensional framework

the P_2O7 groups form clusters with diferent orientations with ABAB mode.Ba atoms coordinate with oxygen atoms to form Ba O10 and BaO11 polyhedra.The experimental results exhibited that the material has a short ultraviolet cutof edge(195 nm)and good thermal stability

and the relationship between the second harmonic generation and the arrangement of anionic groups is discussed emphatically.First-principles calculations elucidated that the optical properties of the compound are mainly derived from the P-O groups.
