Chemical quantum dots are small semiconductor crystallites (1.5 to 5 nm in diameter). Too small to behave as bulk semiconductors, they have band gaps and luminescence colors that vary with size in a controllable and predictable manner. This is the quantum size effect. Quantum dots are essentially new classes of large molecules. This Account describes our efforts to synthesize, characterize, and understand them, starting in 1983 at the Bell Telephone Laboratories in Murray Hill, NJ. The culture and management style of Bell Laboratories was critical to the success of this effort. There was widespread collaboration among scientists of differing backgrounds and interests. Research was carried out entirely with internal AT&T corporate funding. It is doubtful this research could have been successfully carried out in an academic setting at that time.

贝尔实验室的化学量子点



化学量子点是小型半导体微晶(直径 1.5 至 5 nm)。它们太小而无法作为块状半导体,其带隙和发光颜色会随着尺寸以可控和可预测的方式变化。这就是量子尺寸效应。量子点本质上是一类新型大分子。本报告描述了我们从 1983 年开始在新泽西州默里山的贝尔电话实验室开始对它们进行综合、表征和理解的努力。贝尔实验室的文化和管理风格对于这项工作的成功至关重要。不同背景和兴趣的科学家之间进行了广泛的合作。研究完全由 AT&T 公司内部资助进行。这项研究能否在当时的学术环境中成功开展值得怀疑。
