Synthesis and Photoluminescence Spectra of the Composite Films with Cadmium Sulfide Nanocrystals
The paper describes the features of the optical properties of the composite films with embedded cadmium sulfide nanocrystals (NC CdS) which have been obtained in situ via sol-gel method. Photoluminescence spectra comprise two areas: the doped due to surface defects at E 1.6-2.3 eV and exciton at E...

| description | The paper describes the features of the optical properties of the composite films with embedded cadmium sulfide nanocrystals (NC CdS) which have been obtained in situ via sol-gel method. Photoluminescence spectra comprise two areas: the doped due to surface defects at E 1.6-2.3 eV and exciton at E 2.3-3.0 eV. An increase of the precursor Cd(Ас)2∙2H2O concentration in polymer matrix does not bring about automatic increase in the light absorption at max and photoluminescence intensity of the composite film; perhaps this is caused by the formation of less perfect CdS structures in this case. |
