The optical properties of CdSxSe1−x semiconductor nanocrystals (NCs) embedded in glass matrix (SiO2–Na2CO3–B2O3–Al2O3) have been studied by means of optical absorption and photoluminescence (PL) measurements in the temperature range of 5–300 K. The samples were synthesized by conventional fusion method. The images of their atomic force microscopy (AFM) demonstrate an existence of CdSxSe1−x NCs with average diameter of 40Å. Their optical absorption is strongly dependent upon annealing temperature and time. The average size of NCs and the mole fraction x of sulfur have been determined from the detailed analysis of optical absorption spectra based on a simple effective mass theory. The Stokes shift and its relation with the electron-phonon interaction was addressed. |
