【摘要】 <正>纳米科学已经成为涉及物理、化学、材料、生命科学等多领域的交叉学科。由于无机纳米晶材料具有独特的量子尺寸效应,即性质依赖尺寸的效应,它们在光、电、磁、催化,生命科学等领域都展现出诱人的应用前景。尽管纳米晶具有这样多的优良性质,但它们通常以胶体溶液或固体粉末的形式存在,只有将它们分散进相更多还原

【Abstract】 In this paper,we indicate the synthesis and assembly of functional nanocrystals (NCs).First,a series of NCs are prepared using"green chemistry"concept.These NCs include metal,metal oxide,and semiconductor,which can be alternatively synthesized in water and other non-aqueous solvents.High efficiency,low cost,and low toxicity are emphasized in the preparation procedure.Besides,the one-dimension(1D),2D,and 3D assembly of NCs are investigated.1D assembly is driven by the cooperation of one anisotropic interaction and other isotropic interactions.As the anisotropic interaction is weak enough,2D or 3D assembly will occur.Namely,2D assembly is facilitated with the inducement of gas/liquid or liquid/solid interface.Otherwise,3D assembly is favored.更多还原
