Abstract

The nonphotochemical laser-induced nucleation (NPLIN) phenomenon of an inorganic compound, ethylenediamine sulfate, exhibiting crystal chirality has been investigated. Strong enhancement of the nucleation efficiency upon laser irradiation is reported and is shown to rely on the presence of insoluble particles dispersed within the aqueous solutions since filtration drastically reduces the NPLIN effect. Elemental analyses (ICP-OES) show that these particles have a composition close to that of stainless steel. Then, we report a systematic study of the impact of doping the filtered solutions with several types of metallic particles on NPLIN efficiency as a function of irradiation wavelength and show that suitable doping permits to retrieve high nucleation probabilities. The impact of the geometry of light polarization on the distribution of crystal enantiomorphs is also investigated to assess the possibility of stereoselectively triggering the NPLIN effect in the case of ethylenediamine sulfate solutions irradiated with a single nanosecond laser pulse.

非光化学激光诱导成核大大提高硫酸乙二胺水溶液的成核效率——固体杂质在成核机理中作用的研究

研究了具有晶体手性的无机化合物乙二胺硫酸盐的非光化学激光诱导成核现象。据报道，在激光照射下成核效率的显著增强，并且显示依赖于分散在水溶液中的不溶性颗粒的存在，因为过滤显著降低了NPLIN效应。元素分析（ICP-OES）表明，这些颗粒的成分接近不锈钢。然后，我们报道了用几种类型的金属颗粒掺杂过滤溶液对NPLIN效率的影响的系统研究，作为辐射波长的函数，并表明适当的掺杂允许获得高的成核概率。还研究了光偏振的几何形状对晶体对映体分布的影响，以评估在用单纳秒激光脉冲照射乙二胺硫酸盐溶液的情况下立体选择性触发NPLIN效应的可能性。
