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： The silyl phosphine compound of the present invention is represented by the formula (1) and has an arsenic content of not more than 1 ppm. The process for producing a silyl phosphine compound of the present invention is a process comprising mixing a basic compound, a silylating agent and phosphine to obtain a solution containing a silyl phosphine compound, removing a solvent from the solution to obtain a concentrated solution of a silyl phosphine compound, and distilling the concentrated solution, wherein an arsenic content in the phosphine is adjusted to not more than 1 ppm by volume in terms of arsine. The process for producing InP quantum dots of the present invention uses, as a phosphorus source, a silyl phosphine compound represented by the formula (1) and having an arsenic content of not more than 1 ppm by mass. (For definition of R, see the specification.)

摘要： Quantum dots and methods of making quantum dots are described. A method begins with forming quantum dots having a core-shell structure with a plurality of ligands on the shell structure. The method includes exchanging the plurality of ligands with a plurality of second ligands. The plurality of second ligands have a weaker binding affinity to the shell structure than the plurality of first ligands. The plurality of second ligands are then exchanged with hydrolyzed alkoxysilane to form a monolayer of hydrolyzed alkoxysilane on a surface of the shell structure. The method includes forming a barrier layer around the shell structure by using the hydrolyzed alkoxysilane as a nucleation center.

摘要： A bathless plating for a conductive material with composite particles or with high surface coverage. The setup for the bathless electro-plating includes a cathode, a composite mixture, a membrane, and an anode. The cathode is a conductive material. The composite mixture comprises a metal salt, an acid, and a composite material. The composite mixture is applied to the cathode. A hydrophilic membrane is applied to the composite mixture. An anode, with oxidizing properties, is applied to the membrane. A current is applied to the bathless setup. Upon removing the current and composite mixture from the cathode, a metal-based composite coating remains on the cathode.
