Abstract
This article focuses on the nonlinear optical crystal materials in the nano-structure in particular is one-dimensional nanostructures structure of the status quo, And the future prospects of development trends. one-dimensional nanomaterials is to study the electronic transmission, optical and mechanical characteristics of the mechanical properties and other physical properties of the size and dimensions of the ideal system. They will build a nano-electronic and optoelectronic devices such as integrated circuits and functional components in the process of acting as a very important role. At present, major reports on the types of nonlinear optical material nano-structure of the preparation methods, properties and application summary.
