Prof. William E. Buhro, of the Washington University in St. Louis Chemistry Department, is supported by the Division of Chemistry for his research on the effect of the dimensionality (shape) on quantum confinement in quantum wires, rods, and shells, with an emphasis on the study of quantum wires. The development of solution-based techniques for controlling the sizes and shapes of desired materials will facilitate subsequent physical (optical and electronic) characterizations to elucidate the electronic structures and spectroscopic properties of a variety of materials. Shape-controlled nanoscale materials have anticipated applications in nanoelectronics, orientation-sensitive fluorescent labeling, lasing, and light-harvesting cells.Achieving the promise of nanomaterials requires the development of synthetic approaches including solution-based syntheses that yield materials with tailored sizes and shapes. To understand the consequences of the dimensionality (shape) effect on quantum confinement, spectroscopic and physical-properties studies on quantum wires, rods, and shells of various materials will be carried out. The combination of controlled solution-based nanoscale synthesis with physical characterization and spectroscopy will give undergraduates, graduate students, and postdocs a unique training experience in a forefront inorganic materials chemistry program.

华盛顿大学圣路易斯化学系的William E. Buhro教授，因其对量子线、量子棒和量子壳中维度（形状）对量子约束的影响的研究，重点是对量子线的研究，而受到化学系的支持。用于控制所需材料的尺寸和形状的基于溶液的技术的发展将促进随后的物理（光学和电子）表征，以阐明各种材料的电子结构和光谱特性。形状控制的纳米材料有望应用于纳米电子学、取向敏感荧光标记、激光和光收集电池。实现纳米材料的前景需要合成方法的发展，包括基于溶液的合成，以产生具有定制尺寸和形状的材料。为了理解维度（形状）效应对量子约束的影响，将对各种材料的量子线、量子棒和量子壳进行光谱和物理性质的研究。将受控溶液纳米级合成与物理表征和光谱学相结合，将为本科生、研究生和博士后提供最前沿无机材料化学项目的独特培训经验。
