A simple route for tailoring emissions in the visible wavelength region by chemically coupling quantum dots composed of ZnSe and CdS is reported. Coupled quantum dots offer a novel route for tuning electronic transitions via band‐offset engineering at the material interface. This novel class of asymmetric‐coupled quantum structures may offer a basis for a diverse set of building blocks for optoelectronic devices, ultrahigh density memories, and quantum information processing.
