Abstract

The present invention relates to a method for producing metal chalcogenide nanocrystals doped with manganese ions using a precursor consisting of a metal salt which is stable in air and environmentally friendly and, more specifically, to one comprising the steps of: producing a metal-amine complex solution by mixing a manganese salt together with a metal salt other than a manganese salt in an amine-based substance selected from primary amines or secondary amines or mixtures thereof; and adding a celenourea or selenocarbamate and powdered selenium (Se) as a selenium source or else adding powdered sulphur (S) as a sulphur source to the metal-amine complex solution, and mixing and then carrying out a heat treatment. The method of the present invention is advantageous in that it allows high quality doping of impurities into the interiors of nanocrystals, it makes it possible to adjust the size and morphology of, and the extent of impurity doping in the nanocrystals, it is stable and environmentally friendly, and it makes it possible to obtain in volume nanocrystals which are doped with manganese in a single process simply by scaling up.
