摘　　要：Nanoscale amorphous materials are very important member of the non-crystalline solids family and have emerged as a new category of advanced materials. However,morphological control of amorphous nanomaterials is very difficult because of the atomic isotropy of their internal structures. In this review,we introduce some emerging innovative methods to fabricate well-defined,regular-shaped amorphous nanomaterials. We then highlight some examples to evaluate the use of these amorphous materials in electrodes,and their optical response. There is still plenty of room to explore the amorphous world. As researchers continue to advance the scientific tools that underpin the concepts related to 'amorphous',additional applications of these materials will emerge. Their controlled synthesis will undoubtedly attain new heights in the discipline of nanomaterials,and allow nanoscale amorphous materials to become more sophisticated,diverse,and mainstream.非晶纳米材料是非晶态物质中十分重要的成员,并已成为先进材料研究领域的一个崭新分支.然而,实现对非晶纳米材料的形貌控制却是十分困难的,这是由材料原子排列的长程无序性所致.本综述首先介绍了一些最近出现的新颖和独特的非晶纳米材料的制备方法.由以上方法所得到的非晶纳米材料具有轮廓分明、形貌规则等特点,摆脱了传统非晶材料呈现的无规则状颗粒或者薄膜的局限.本文选取了一些有特色的新颖的非晶纳米材料,来说明现阶段它们在电化学电极材料以及光响应方面的应用原理以及方式.如今,国内外对于非晶纳米材料的研究刚刚起步,仍然有很大的探索空间.研究者不断开发和创造出来的科学方法和技术将有利于非晶研究的快速发展,进而开发新的应用.非晶纳米材料的可控制备必将掀起纳米领域研究的新高潮.
