Abstract

CuInS₂ microspheres have been prepared via a solvothermal route employing synthetic In₂S₃ microspheres as templates. X-ray diffraction analysis reveals that CuInS₂ crystals assembled from In₂S₃ microsphere building blocks are tetragonal phase. Field emission scanning electron microscopy and transmission electron microscopy images show that the prepared CuInS₂ microspheres are constructed by nanosheets. The evolution of crystal structure could be attributed to Cu⁺ ions inserted into the In₂S₃ microsphere templates, such that some In³⁺ ions were replaced and tetragonal CuInS₂ crystals were formed during the solvothermal process.
