摘 要：<正>One-dimensional（1-D）nanostructures have been attracted much attention as a result of their exceptional properties,which are different from bulk materials.Among 1-D nanostructures,1-D heterostructures with modulated compositions and interfaces have recently become of particular interest with respect to potential applications in nanoscale building blocks of future optoelectronic devices and systems.Many kinds of methods have been developed for the synthesis of 1-D nanoscale heterostructures.This article reviews the most recent development,with an emphasize on our own recent efforts,on 1-D nanoscale heterostructures,especially those synthesized from the vapor deposition methods,in which all the reactive precursors are mixed together in the reaction chamber.Three types of 1-D nanoscale heterostructures,defined from their morphologies characteristics,are discussed in detail,which include 1-D co-axial core-shell heterostructures,1-D segmented heterostructures and hierarchical heterostructures.This article begins with a brief survey of various methods that have been developed for synthesizing 1-D nanoscale heterostructures and then mainly focuses on the synthesis,structures and properties of the above three types of nanoscale heterostructures.Finally,this review concludes with personal views towards the topic of 1-D nanoscale heterostructures.
