Abstract:

The layered double hydroxide(LDH) compounds Cd 0.7 Cr 0.3(OH)2(C12H25SO4)0.3·0.7H2O and Zn 0.5 Cd 0.25 Cr 0.25 (OH)2(C12H25SO4) 0.25 ·1.7H2O were synthesized. Using these compounds as the precursors, we prepared CdS and CdS/ZnS nanocrystals that are implanted and stabilized in the layer matrices of the two types of compounds via a gas/solid reaction. The size of the nanocrystals can be controlled and tuned by changing the Cd/Cr molar ratio in the precursor.

Key words: Cr-contained hydrotalcite; Cadmium sulfide; Zinc sulfide; Nanocrystals
