Abstract

The formation and growth specifics of metal fluoride MF₂ (where M = Ca, Sr, or Pb) and MF₃ (where M = Sc, La, or Ln) crystals by reacting components of aqueous metal salt solutions with hydrogen fluoride gas at the planar solution–gas interface at room temperature are considered. Compounds with different crystal structures: PbF₂ (space groups Pnma and Fm\(\bar {3}\)m), ScF₃ (sp. gr. Pm\(\overline{3}\)m and P6/mmm), and LaF₃ (space group \(P\bar {3}c\)1) were chosen as objects of study. The factors having a significant influence on the morphology, size, and ordering of the grown crystals have been identified. An opportunity to prepare 1D and 2D crystals has been shown for some compounds. Probable applications fields of nanomaterials based on the prepared compounds are analyzed. The conclusion is made about a potential of the interface technique for use in the design of new solid electrolytes, optically active materials, and functional coatings.

新型无机氟化物纳米材料在软化学条件下的结晶及其应用前景

摘要研究了金属氟化物 MF2（其中 M = Ca、Sr 或 Pb）和 MF3（其中 M = Sc、La 或 Ln）晶体的形成和生长特性，这些晶体是通过金属盐水溶液中的组分与氟化氢气体在室温下的平面溶液-气体界面上发生反应而形成的。具有不同晶体结构的化合物选择了 PbF2（空间群 Pnma 和 Fm\(\bar {3}\)m）、ScF3（空间群 Pm\(\overline{3}\)m 和 P6/mmm）和 LaF3（空间群 \(P\bar {3}c\)1）作为研究对象。已经确定了对生长晶体的形态、尺寸和有序性有重大影响的因素。一些化合物有机会制备出一维和二维晶体。分析了基于所制备化合物的纳米材料的可能应用领域。最后得出结论：界面技术在设计新型固体电解质、光学活性材料和功能涂层方面具有潜力。
