Zusammenfassung:The spherical particles CdSexS1-x with 30-80nm in radius have been successfully prepared by the hydrothermal reaction at 200 deg C. The structure characterization which has been carried out using X-ray diffraction (XRD) shows hexagonal crystal structure. Novel properties have been observed via UV-visual absorption spectra and photoluminescence (PL) spectra. The absorption shoulder and the luminescence emission peaks have been tuned by changing the mole ratio of Se in the CdSexS1-x samples.
