驰使

而质子溶剂H2O/HAc中质子浓度的增大使得MC/Eu（Ⅲ）配合物周围的溶剂笼产生重组，溶剂驰豫使其荧光光谱波长的Stokes位移增大；

The increase in the H ~ + concentration of H_2O / HAc solvent results in a reorientation of the solvent cages around MC / Eu (ⅲ) complex as well as a great Stokes shift of the fluorescent spectrum due to the solvent relaxation ;

结果表明，结构驰豫使系统能量下降，原子向表面一侧扩散。

The results show that the structural relaxation of the surface reduces the system energy of the substrate .

晶体场劈裂能的绝对值在单轴应力作用下大约2GPa时达到最小值，受限的单轴应力较自由驰豫时使价带顶的分裂加剧，但直接带隙的性质没有变化。

The absolute values of the crystal-field splitting energy are minimum at 2 GPa for the free uniaxial stress . The restricted uniaxial stress pricks up the splitting of the valence band , but the direct-band gap does not change .
