Nanomaterials Chemistry: Creating a Universe in a Grain of Sand

【Abstract】

Chemical routes now exist to produce nanocrystal materials with a wide range of size, shape and composition. These materials have characteristic dimensions that are at least 1,000 times smaller than a human hair and exhibit a wide range of unique properties due to their size. For example, semiconductor nanocrystals or quantum dots exhibit size-tunable optical properties that are useful for light-emitting and light-absorbing applications. Semiconductor nanowires have attributes of polymers like mechanical flexibility combined with the useful electronic and optical properties of semiconductors in one material. This presentation will highlight some of our work on the synthesis of silicon, germanium and lead halide perovskite nanomaterials, their assembly into superlattices and films, and their use in applications ranging from biological cell imaging to paper solar cells to lithium-ion batteries.

我们现在能够通过化学合成的方法来制备具有不同尺寸、形状和组分的纳米晶材料。这些材料在尺度上至少比人类头发丝小1000倍，并由于其纳米级别的尺寸展现出独特的性质。例如，半导体纳米晶或量子点在不同尺寸下拥有可以调节的光学性质，适用于在发光和吸光领域的应用。半导体纳米线在具有聚合物的机械柔韧性同时，展示出特殊的半导体光电性能。本次报告将重点介绍我们实验室基于硅、锗和铅卤化物钙钛矿等纳米材料的合成、超晶格和薄膜组装的工作，并将展示这些材料在生物细胞成像、纸质太阳能电池和锂离子电池等领域的应用。
