Abstract

The concept of ion-exchange transformation in heterogeneous thin film–aqueous solutions of metal substituents is presented as a promising way of synthesizing multicomponent compounds based on metal chalcogenides. Characteristic features of this process are described and a number of its physicochemical patterns are revealed using data obtained at Yeltsin Ural Federal University’s Faculty of Physical and Colloid Chemistry with thin-film solid solutions of Sn_xPb_1–xSe, Cd_xPb_1–xS, Ag_xPb_1–xS, Hg_xPb_1–xSe, Sn_xPb_1–xS of different compositions. The organization of ion-exchange synthesis is considered, starting from preliminary calculations and ending with interpretation of the final results. The effect the temperature, the morphology and crystal structure of the initial film, the composition of aqueous solution, and the metal substituent have on the depth of the process is described. Data on the solid-phase diffusion of lead ions in a CdS film are presented.

离子交换转化金属硫属元素化物固溶体的目标合成

摘要

提出了金属取代基的异质薄膜-水溶液中的离子交换转化的概念，这是一种基于金属硫族化物合成多组分化合物的有前途的方法。描述了该过程的特征，并利用在叶利钦乌拉尔联邦大学物理与胶体化学学院获得的数据以及Sn _x Pb _{1– x} Se，Cd _x Pb _1–薄膜固溶体获得的数据揭示了该过程的许多物理化学模式。_x S，Ag _x Pb _{1– x} S，Hg _x Pb _{1– x} Se，Sn _x Pb _{1– x}组成不同的S。从初步的计算开始，到对最终结果的解释结束，都考虑了离子交换合成的组织。描述了温度，初始膜的形态和晶体结构，水溶液的组成以及金属取代基对工艺深度的影响。介绍了有关CdS膜中铅离子固相扩散的数据。
