This study examines the feasibility of neutron-induced nuclear transmutation for producing indium-doped tin materials using SnCl as a model system. Neutron irradiation resulted in structural modifications, including morphological changes, lattice expansion, and the formation of indium-containing crystalline phases. Scanning Electron Microscopy (SEM) and Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) confirmed the presence of indium at approximately 0.88 at. % postirradiation, with a uniform distribution across the material. X-ray Diffraction (XRD) and Raman spectroscopy provided additional evidence of structural changes, supporting the successful incorporation of indium into the SnCl matrix. These results indicate that nuclear transmutation can be used to produce indium-doped tin materials, offering an alternative approach for synthesizing materials relevant to advanced applications. The process utilizes the neutron capture properties of chlorine to control neutron penetration, contributing to the development of materials with specific characteristics.
本研究以SnCl为模型体系,考察了中子诱导核嬗变制备铟掺杂锡材料的可行性。中子辐照导致了结构改性,包括形态变化、晶格膨胀以及含铟晶相的形成。扫描电子显微镜(SEM)和电感耦合等离子体发射光谱(ICP-OES)证实,辐照后铟的含量约为0.88原子%,且在材料中分布均匀。X射线衍射(XRD)和拉曼光谱提供了结构变化的额外证据,支持铟成功掺入SnCl基体。这些结果表明,核嬗变可用于制备铟掺杂锡材料,为合成与先进应用相关的材料提供了一种替代方法。该过程利用氯的中子俘获特性来控制中子穿透,有助于开发具有特定特性的材料。
