Abstract The preferred crystallographic orientation of nanocrystals plays a significant role in determining their properties. From the wide variety of nanocrystal growth techniques, we focus in this paper on crystal growth by precipitation from liquid solutions inside porous substrates, and discuss the progress that has been made during the last decade concerning the control of crystal growth direction through this method. In this overview, the motivation and principal mechanisms of achieving highly oriented nanocrystals are presented. Moreover, different experimental challenges within the described growth technique are probed. The paper presents the thermodynamic and kinetic considerations for favoring crystal growth inside pores rather than bulk growth. A special focus is made on the origin of obtaining preferred crystallographic orientations in various types of materials, including varying perspectives of thermodynamic and kinetic driving forces. The paper ends with technological application of crystal growth with preferred crystallographic orientation inside nano-pores.

嵌入纳米孔内的纳米晶体的优选晶体取向

摘要 纳米晶体的择优晶向在决定其性质方面起着重要作用。从各种各样的纳米晶体生长技术中，我们在本文中重点介绍了通过从多孔基材内的液体溶液中沉淀出来的晶体生长，并讨论了在过去十年中通过这种方法控制晶体生长方向取得的进展。在此概述中，介绍了实现高度取向纳米晶体的动机和主要机制。此外，还探讨了所描述的生长技术中的不同实验挑战。该论文提出了有利于孔内晶体生长而不是体生长的热力学和动力学考虑因素。特别关注在各种类型的材料中获得优选晶体取向的起源，包括热力学和动力学驱动力的不同视角。论文以在纳米孔内具有优选晶体取向的晶体生长技术应用结束。
