Effect of the nature of dispersion medium on the CdTe/TGA nanocrystal formation in colloidal solutions and polymeric membranes

Abstract

In this work, physical and chemical properties of CdTe low-dimensional crystallites obtained by grinding or colloidal synthesis have been investigated. In particular, we have analyzed the photoluminescent characteristics of CdTe nanocrystals stabilized by thioglycolic acid, synthesized by using deionized water and water solutions of ethylene glycol and glycerin of different concentrations as dispersion medium. It has been shown that the stability of colloidal solutions of CdTe nanocrystals depends on the nature of dispersion medium and the stabilizer concentration.
