Abstract

The invention relates to methods for producing PbS nanocrystals, in particular to a method for producing hydrophilic PbS nanocrystals.The method, according to the invention, includes the homogenization of PbS nanocrystals, stabilized by oleic acid, in a nonpolar solvent, the boiling point of which is below the water boiling point in a ratio of 25 mg/ml, treatment of the obtained solution with 0.05...1.0 N solution of lithium or sodium, or potassium, or rubidium hydroxide, heating of the obtained mixture at the temperature of 50...60°C up to its staining in an intense black and brown colour, the gradual increase of temperature to the boiling of nonpolar solvent and maintenance of boiling up to its complete evaporation.
