Photoluminescent Properties of CdTe Nanocrystals in Colloidal Solutions and Polymer Films
Journal Title: Фізика і хімія твердого тіла - Year 2016, Vol 17, Issue 1
Abstract
Using stabilizers and promoters we have obtained colloidal CdTe nanocrystals (NCs) in aqueous solutions. Incorporation of the CdTe NCs into polymer films has been fulfilled subsequently. It is shown that the use of vinyl acetate-acrylate copolymer as the matrix material for CdTe NC incorporation from colloidal solutions allows to get stable and nontoxic nanoheterogeneous film structures, which are characterized by satisfactory values of the photoluminescence quantum yield. Photoluminescence characteristics of the studied materials have been analyzed.
