  • Method for preparation of magic-sized nano-crystalline substance
    Patent number: 10865109
    Abstract: A method for preparing a magic-sized nano-crystalline substance, wherein a component containing at least one metal element of groups IIB, IIIA and IVA in the periodic table, and a component containing at least one non-metal element of groups VIA and VA are used as raw materials. In a reaction system for preparing a conventional nano-crystalline substance and in an inert gas atmosphere, after heating the reaction, reactants are cooled to a temperature 50% lower than the actual heating temperature of the reaction thereof, and after standing, the target product of the magic-sized nano-crystalline substance is obtained. The required pure target product can be obtained by the preparation method.
