Abstract
A quantum dot structure includes a core and an inner shell. The core is a single crystal of a compound M1C1, and has a core surface having a first region and a second region. The first region has a crystal plane that is inactive with oxygen, and the second region has a crystal plane that is easily reactive with oxygen. The inner shell is a single crystal of a compound M2C2, and is formed on the first region of the core surface. A method for making the quantum dot structure is also disclosed.
