norganic composite CdS/heteropolyanion nanoparticles with salt-like structures

Using the reaction between Cd3(PW12O40)2 and Na2S, composite CdS nanoparticles with heteropolyanions of PW12O403− as balance charge (named as CdS/PW12O403−) were synthesized. The electron conductivity behavior of the compound was similar to a strong electrolyte in solution. A salt-like structure was proposed for this kind of nanoparticles.
