Optical investigations of thermostimulated changes in an ensemble of CdSxSe₁₋x quantum dots embedded into borosilicate glass matrix

Optical investigations of thermostimulated changes in an ensemble of CdSxSe₁₋x quantum dots embedded into borosilicate glass matrix

We have employed the absorption and Raman spectroscopies to study thermostimulated changes in an ensemble of CdSXSe₁₋X quantum dots embedded into a borosilicate glass matrix. It is shown that additional annealing of the sample containing CdSXSe₁₋X quantum dots leads to growth of the new ones with hi...
