    EFFECTS OF HEAT TREATMENT ON MORPHOLOGICAL AND OPTICAL PROPERTIES OF ZnS NANOCRYSTALS EMBEDDED IN KBr MATRIX.
    (University of Eloued جامعة الوادي, 2018-02-05) ZEROUAL, S.; MAHBOUB, M.S.; SEBAIS, M.
    ZnS nanocrystals were embedded in KBr single crystal matrix using Czochralski growth technique. The X-ray diffraction and optical spectroscopy revealed the incorporation of ZnS nanocrystals. A blue shift of the absorption edge of the obtained samples has been observed indicating the quantum confinement effect. Annealing led to a shift in the absorption edge towards longer wavelengths and an increasing of the emissions intensity. This results shows that KBr is a good matrix-host of ZnS nanocrystals and that the elaborated samples can be used for important technological applications.
