Single-crystalline trumpetlike zinc phosphide nanostructures

Single-crystalline trumpetlike Zn3 P2 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 Zn3 P2 nanowires with diameters of ∼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 Zn3 P2 nanostructures shows a broad emission centered at ∼585 nm at room temperature.
