Abstract
Present invention provides a process for the synthesis of size and composition tunable colloidal PbMgS core and PbMgS/MS core shell quantum dots emitting in the near infrared (NIR) region of the spectrum in a single operation in a continuous flow reactor. M includes at least one of Cd, Mg, Zn and Cu metals.
Claims22
A composition, comprising:
- a nanostructure;
- and
- a surfactant bound to a surface of the nanostructure, the surfactant including an oil-dispersible polymer containing a functional group, wherein the oil-dispersible polymer includes polyethylene-co-acrylic acid (PECA),
- wherein the nanostructure includes a core shell quantum dot with PbxMg1-xS core and a semiconductor shell comprising MS, M being metal and selected from the group consisting of Mg, Cd, Zn and Cu and a combination thereof, where x value is between 0.7 and 0.95.
