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.

我們現在能夠通過化學合成的方法來制備具有不同尺寸、形狀和組分的納米晶材料。這些材料在尺度上至少比人類頭發絲小1000倍，并由于其納米級別的尺寸展現出獨特的性質。例如，半導體納米晶或量子點在不同尺寸下擁有可以調節的光學性質，適用于在發光和吸光領域的應用。半導體納米線在具有聚合物的機械柔韌性同時，展示出特殊的半導體光電性能。本次報告將重點介紹我們實驗室基于硅、鍺和鉛鹵化物鈣鈦礦等納米材料的合成、超晶格和薄膜組裝的工作，并將展示這些材料在生物細胞成像、紙質太陽能電池和鋰離子電池等領域的應用。
