摘要： Quantum dot semiconductor nanoparticle compositions that incorporate ions such as zinc, aluminum, calcium, or magnesium into the quantum dot core have been found to be more stable to Ostwald ripening. A core-shell quantum dot may have a core of a semiconductor material that includes indium, magnesium, and phosphorus ions. Ions such as zinc, calcium, and/or aluminum may be included in addition to, or in place of, magnesium. The core may further include other ions, such as selenium, and/or sulfur. The core may be coated with one (or more) shells of semiconductor material. Example shell semiconductor materials include semiconductors containing zinc, sulfur, selenium, iron and/or oxygen ions.

摘要： A process is disclosed for producing quantum dots (QDs) by reacting one or more core semiconductor precursors with phosphine in the presence of a molecular cluster compound. The core semiconductor precursor(s) provides elements that are incorporated into the QD core semiconductor material. The core semiconductor also incorporates phosphorus, which is provided by the phosphine. The phosphine may be provided to the reaction as a gas or may, alternatively, be provided as an adduct of another material.
