Systematic Synthesis of Tellurium Nanostructures and Their Optical Properties: From Nanoparticles to Nanorods, Nanowires, and Nanotubes

Abstract In the past two decades, tremendous efforts have been made towards the development of synthetic strategies for nanostructured materials with well‐controlled size, shape, composition, and spatial arrangement. Herein, we report a systematic study on the synthesis of tellurium nanostructures, which can evolve from nanoparticles to nanorods, nanowires, and nanotubes by a simple solution‐based process. The size‐ and diameter‐dependent optical properties of Te nanowires have been explained based on the modeling calculations using the joint density of states (JDOS).
