摘要

Abstract-Two phase thin-film composites consisting of CdxPb1 - xS (0.007 ≤ x ≤ 0.068) substitutional solid solutions with a B1 cubic structure (sp. gr.).\(Fm/bar{3}m/)）和无定形硫化镉（CdS）的取代固溶体。原子力显微镜对薄膜的表面形貌进行了研究，研究结果被用来计算表面微形貌参数。研究发现了 CdS-PbS 薄膜的成分与功能特性之间的相关性。首次评估了 CdxPb1 - xS/CdS 两相薄膜对空气中氨气 (NH3) 的灵敏度。氨的室温检测限被确定为 10 ppm（6.22 mg/m3）。

Sensing Properties of CdxPb1 – xS/CdS Thin-Film Structures Produced by Chemical Deposition

Two-phase thin-film composites consisting of Cd_xPb_{1 –} _xS (0.007 ≤ x ≤ 0.068) substitutional solid solutions with a B1 cubic structure (sp. gr. \(Fm\bar {3}m\)) and amorphous cadmium sulfide (CdS) have been produced by chemical deposition. The surface topography of the films has been studied by atomic force microscopy, and the results have been used to calculate surface microtopography parameters. A correlation has been found between the composition and functional properties of thin CdS–PbS films. The sensitivity of Cd_xPb_{1 –} _xS/CdS two-phase films to ammonia (NH₃) in air has been assessed for the first time. The room-temperature detection limit for ammonia has been determined to be 10 ppm (6.22 mg/m³).

期刊介绍： Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
