Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing nanometer-scale InP particulates efficiently and industrially advantageously in a short time, and also to provide a dispersion of the InP particulates. SOLUTION: This method comprises reacting, in a solvent, an In-basic ingredient comprising two or more In-compounds with a P-ingredient comprising at least one P-compound to produce InP particulates. The above two or more In-compounds comprise at least one first In-compound which has a group to be removed by reacting with a functional group of the P-compound having P atoms adjacent to In atoms upon the formation of the In-P bond, and at least one second In-compound which has an electron density lower than that of the first In-compound in the In atom in the compound. As for the above solvent, a Lewis basic solvent is used. Besides, the dispersion of the InP particulates obtained by the above method is also provided. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a new and useful nanocrystallite. SOLUTION: The method of manufacturing a nanocrystallite comprises: a process in which a metal M or an M containing salt and a reducing agent are contacted to form an M-containing precursor, wherein M is Cd, Zn, Mg, Hg, Al, Ga, In or Tl; a process in which the M-containing precursor is made by being contacted with X donors to, form a mixture, wherein X is O, S, Se, Te, N, P, As or Sb; and a process in which the mixture is heated under the presence of amines to form a nanocrystallite.
