One dimensional (1D) nanostructures of semiconducting oxides and elemental chalcogens culminate over the last decade in nanotechnology owing to their unique properties exploitable in several applications sectors. Whereas several synthetic strategies have been established for rational design of 1D materials using solution chemistry and high temperature evaporation methods, much less attention has been given to the laser-assisted growth of hybrid nanostructures. Here, we present a laser-assisted method for the controlled fabrication of Te nanotubes. A series of light-driven phase transition is employed to controllably transform Te nanotubes to core-Te/sheath-TeO(2) and/or even neat TeO(2) nanowires. This solid-state laser-processing of semiconducting materials apart from offering new opportunities for the fast and spatially controlled fabrication of anisotropic nanostructures, provides a means of simultaneous growing and integrating these nanostructures into an optoelectronic or photonic device.
一维（1D）半导体氧化物和元素硫属化物纳米结构在过去十年中由于其在多个应用领域的独特性能而在纳米技术中达到顶峰。虽然已经建立了几种使用溶液化学和高温蒸发方法的 1D 材料的合理设计的合成策略，但对激光辅助生长杂化纳米结构的关注却很少。在这里，我们提出了一种用于控制 Te 纳米管制备的激光辅助方法。一系列光驱动的相变被用来可控地将 Te 纳米管转化为核-Te/鞘-TeO(2)甚至纯 TeO(2)纳米线。除了为快速和空间控制的各向异性纳米结构制造提供新的机会外，这种半导体材料的固态激光加工还提供了将这些纳米结构同时生长并集成到光电或光子器件中的手段。
