Acetic acid-confined synthesis of uniform three-dimensional (3D) bismuth telluridenanocrystals consisting of few-quintuple-layer nanoplatelets

Abstract

High-selectivity, uniform three-dimensional (3D) flower-like bismuth telluride (Bi₂Te₃) nanocrystals consisting of few-quintuple-layer nanoplatelets with a thickness down to 4.5 nm were synthesized for the first time by a facile, one-pot polyol method with acetic acid as the structure-director. Micrometre-sized 2D films and honeycomb-like spheres can be obtained using the uniform 3D Bi₂Te₃ nanocrystals as building blocks.
