| Popis: | The glass system SiO2 B2O3 ZnO Na2O K2O with the addition of CdSSe semiconductor was synthesized by the conventional melt-quench method. The growth of QDs was confirmed using XRD, micro-Raman, and HRTEM study. The structural modification occurs in glass matrix due to nanocrystal growth has been studied from FTIR spectra. The optical properties of CdSSe quantum dots (QDs) grown in borosilicate glass matrix are investigated. The tuning of band gap of CdSSe QDs by controlled heat treatment is reported in the present study. |
