Sub-nanoparticles (SNPs) exhibit unique properties and functions due to their extremely small particle size reaching a quantum scale. Although the synthesis of SNPs requiring precise control of atomicity and composition has not been accomplished, we recently developed the atom-hybridization method (AHM) realizing such atomic-level control us-ing a macromolecular template. As the next step toward the quest for the innovative quantum materials, the practical creation of functional sub-nanomaterials will become the central subject. In this study, we newly established the screening technique for the functional SNPs by focusing on the simple indium-tin binary system with sequential compositions using the latest AHM. As a result, it was revealed that the thermodynamically unstable indium species is produced only at a certain composition leading to the durable luminescent function. Such the phenomenon in the sub-nanosized substances will play an important role in the development of the as-yet-unknown field of quantum materials.

杂原子性序贯筛选技术探索量子材料

亚纳米粒子 (SNP) 由于其达到量子尺度的极小粒径而表现出独特的性质和功能。尽管需要精确控制原子性和组成的 SNP 的合成尚未完成，但我们最近开发了使用大分子模板实现这种原子级控制的原子杂交方法 (AHM)。作为寻求创新量子材料的下一步，功能性亚纳米材料的实际创造将成为中心课题。在这项研究中，我们通过使用最新的 AHM 专注于具有顺序组成的简单铟锡二元系统，新建立了功能 SNP 的筛选技术。因此，结果表明，热力学不稳定的铟物质仅在特定组成下产生，从而导致持久的发光功能。亚纳米级物质中的这种现象将在量子材料尚未为人所知的领域的发展中发挥重要作用。
