Self-assembled synthesis and surface photovoltage properties of polyhedron-constructed micrometer solid sphere and hollow-sphere In2S3†
Abstract
β-In2S3 solid micro-spheres composed of wedge-like octahedra, and hollow micro-spheres composed of nanorods have been fabricated by a simple one-step hydrothermal treatment. The unique surface photovoltage properties of the as-prepared In2S3 samples were investigated through surface photovoltage (SPV) spectroscopy.
