中文摘要:
      为设计品优的非线性光学材料,我们把两个碱土金属原子掺杂于(NH2CH34形成了碱土金属类无机碱金属化合物——Be (NH2CH34M (M=Be,Mg和Ca),和已被合成的Li (NH2CH34Na类似,Be (NH2CH34M (M=Be,Mg和Ca)的外侧碱土金属的NBO电荷是负值,这说明它们展现出了良好的碱土金属类无机碱金属化合物特征。Be (NH2CH34M (M=Be,Mg和Ca)同时还具有相当大的静态第一超极化率(β0),其中最大值为657794(6.58×105) au (Be (NH2CH34Be)。所有的具有碱土金属类无机碱金属化合物特征的Be (NH2CH34M (M=Be,Mg,和Ca)比具有无机碱金属化合物特征的Li (NH2CH34M'(M'=Li,Na和K)有更大的β0值。这些说明对于增加非线性光学响应来说,碱土金属原子掺杂是一种品优的方式。
英文摘要:
      For designing high-performance nonlinear optical (NLO) materials, two alkaline earth metal atoms were doped into the (NH2CH3)4 cluster to form the inorganic alkaline earth-based alkalides Be(NH2CH3)4M (M=Be, Mg, and Ca). Similar to the alkalide characteristics of the synthesized Li+(NH2CH3)4Na-, the NBO charges of the outer alkaline earth metal atoms are negative, which indicates these Be+(NH2CH3)4M- present unusual alkaline earth-based alkalide's features. They also exhibit dramatically large static first hyperpolarizability (β0) up to 657794(6.58×105) au (Be(NH2CH3)4Be). All the β0 values of Be(NH2CH3)4M with alkaline earth-based alkalide features are much larger than that of the Li(NH2CH3)4M' (M'=Li, Na, and K) with alkalide features. These suggest that the alkaline earth metal atom doping is a well-performance method to enhance the NLO responses.
