| Abstract: | Under the optimized experimental conditions, the reverse mieroemulsion method was employed to prepare CdS nanocrystals. The influence of the pH value of solution, the concentration of reactants and temperature on the size of CdS nanocrystals were investigated. Transmission electron microscopy（TEM）, X-ray diffraction（XRD） and Raman speetra（Raman） techniques were used to characterize particle diameter and structure of nanocrystals. The results showed that the CdS nano- crystals with narrow sized distribution were cubic structure of zinc blende, the diameter of nanocrys- tals is about 3--5nm and they have good dispersion. |
