Abstract
A quantum dot, and a quantum dot composite and a device including the same are disclosed, wherein the quantum dot includes a template including a first semiconductor nanocrystal, a quantum well (e.g., quantum well layer) disposed on the template and a shell disposed on the quantum well, the shell including a second semiconductor nanocrystal, and wherein the quantum dot does not include cadmium, wherein the first semiconductor nanocrystal includes a first zinc chalcogenide, wherein the second semiconductor nanocrystal includes a second zinc chalcogenide, and the quantum well layer includes an alloy semiconductor nanocrystal including indium (In), phosphorus (P), zinc (Zn), and a chalcogen element wherein a bandgap energy of the alloy semiconductor nanocrystal is less than a bandgap energy of the first semiconductor nanocrystal and less than a bandgap energy of the second semiconductor nanocrystal.
