Exploring the photophysical properties of CdS core and CdS@ZnS core–shell quantum dots for Hg ²⁺ -ion sensing and phosphor-converted white LED applications

Here, we have reported the synthesis of CdS core and CdS@ZnS core–shell QDs using N -acetyl-

-cysteine as a capping agent. These QDs were explored as a fluorometric detection of mercury ion as well as for phosphor-converted white LED applications.
