Abstract EN
A novel methodology for the direct synthesis of CdS nanoparticles, using a biological agent that avoids the extracellular processing, and the results of the characterization of CdS nanocrystals are presented.
The by-products of the anaerobic respiratory process of Desulfovibrio alaskensis 6SR along with aqueous solutions of Cd salts were successfully employed to produce CdS nanocrystals with mixed cubic and hexagonal phases.
Nanocrystal size has a narrow size distribution with little dependence on the Cd concentration.
Both the presence of the crystallographic cubic phase and the crystalline order decrease as Cd concentration increases.
The band gap values obtained from optical transmission measurements are lower than those of the bulk crystal.
Raman spectroscopy characterization agrees with electron transmission microscopy images and X-ray diffraction results indicating that the method promotes the formation of high structural quality nanocrystals when low concentrations of the Cd salt are used.
