Single-crystalline trumpetlike zinc phosphide nanostructures

Single-crystalline trumpetlike Zn3P2 nanostructures composed of hollow cones supported by nanowires have been prepared via a simple thermochemical method, which utilized ZnS and GaP as the source materials. The as-synthesized nanostructures are composed of single-crystalline Zn3P2 nanowires with diameters of similar to 50 nm and large diameter hollow cones with diameters increasing from 50 nm at the bottom to 600 nm at the top. Photoluminescence study of the trumpetlike Zn3P2 nanostructures shows a broad emission centered at similar to 585 nm at room temperature.
