The synthesis of one-dimensional(1D)semiconductor nanostructures has been studied intensively for a wide range of materials due to their unique structural and physical properties and promising potential for fu- ture technological applications.Among various strategies for synthesizing ID semiconductor nanostructures, solution-phase synthetic routes are advantageous in terms of cost,throughput,modulation of composition, and the potential for large-scale and environmentally benign production.This article gives a concise review on the recent developments in the solution-phase synthesis of 1D semiconductor nanostructures of different compositions,sizes,shapes,and architectures.We first introduce several typical solution-phase synthetic routes based on controlled precipitation from homogeneous solutions,including hydrothermal/solvothermal process,solution-liquid-solid(SLS)process,high-temperature organic-solution process,and low-temperature aqueous-solution process.Subsequently,we discuss two solution-phase synthetic strategies involving solid tem- plates or substrates,such as the chemical transformation of 1D sacrificial templates and the oriented growth of 1D nanostructure arrays on solid substrates.Finally,prospects of the solution-phase approaches to 1D semiconductor nanostructures will be briefly discussed.
