Keywords:quantum dot, Nano Quantum Devices

By coating PbS quantum dots with a thin silica coating by thermal forced decomposition and then forming a thick silica shell by the reverse micellar method, we have realized QDs of various sizes with high luminous efficiency that can be used for position control.
