Abstract

We report synthesis of a novel metal-semiconductor heterostructure, in which AuAg alloy nanoparticles locate at Ag2S quantum tube tips. Ag2S quantum tubes have ultrathin walls below 1 nm thickness. The formation mechanism, UV-vis, luminescence and photoelectrochemical activity of the prepared heterostructure were further studied.
