摘要

摘要/ abstract摘要:介绍了以亚硫酸钠和硫酸锌为基材的水溶液中电化学沉积硫化锌的研究进展，确定了电化学合成硫化锌薄膜的条件。ZnS沉积的电位范围被限制在电流达到与亚硫酸盐离子扩散限制的电化学还原相关的临界值的电位。合成的薄膜含有过量的硫，可以通过热处理去除，以获得化学计量正确的薄膜。提出了一种导致硫化锌生成的反应机理。

Electrochemical Deposition of Zinc Sulfide from a Na2SO3-Based Electrolyte

Abstract—

Aspects of electrochemical deposition of zinc sulfide from an aqueous electrolyte based on sodium sulfite and zinc sulfate are addressed, and conditions for electrochemical synthesis of ZnS films are identified. The range of potentials for ZnS deposition is demonstrated to be limited by the potential at which the current reaches the critical value associated with diffusion-limited electrochemical reduction of the sulfite ion. The synthesized films are found to contain excess sulfur, which can be removed by thermal treatment to obtain stoichiometrically correct films. A reaction mechanism leading to the formation of zinc sulfide is proposed.
