METHOD OF INCREASING STABILITY OF AQUEOUS SOLUTION OF QUANTUM DOTS - CADMIUM SELENIDE NANOPARTICLES COATED WITH MERCAPTO ACIDS

摘要

FIELD: chemistry.;SUBSTANCE: aqueous solution of quantum dots based on cadmium selenide coated with mercapto acids is stabilised by adding sodium sulphite until achieving its concentration of 0.02-0.2 mol/l in the solution.;EFFECT: high stability of aqueous solution of quantum dots while preserving luminescence brightness, hydrodynamic diameter and active groups of the quantum dots.;2 dwg
