Abstract

AbstractCdTe quantum dots embedded in glass matrix are grown using two‐step annealing method. The results for the optical transmission characterization are analysed and compared with the results obtained from CdTe quantum dots grown using conventional single‐step annealing method. A theoretical model for the absorption spectra is used to quantitatively estimate the size dispersion in the two cases. In the present work, it is established that the quantum dots grown using two‐step annealing method have stronger quantum confinement, reduced size dispersion and higher volume ratio as compared to the single‐step annealed samples.
