We report the synthesis and characterization of a unique CdS architecture made of two intersecting ribbons that form a ridge-shaped bicrystalline CdS nanoribbon via simple thermal evaporation of CdS powder. The CdS bicrystalline nanoribbons have a tapering width decreasing from 600 to 50 nm and lengths of several tens of micrometers. The nanostructures show strong band gap emission and weak defect-related emission. Zigzag CdS bicrystalline nanoribbons are occasionally formed at the tip region.
