Hydrothermal synthesis and photoluminescent properties of stacked indium sulfide superstructures

Abstract

Unusual hierarchical stacked superstructures of cubic β-In₂S₃ were fabricated via a facile hydrothermal process in the presence of a surfactant cetyltrimethylammonium bromide CTAB; the 3D superstructures were developed by helical propagation of surface steps from microflakes of 10–20 nm thickness.
