Effects of Zn (II) on the optical properties of CdTe quantum dots and their photoluminescence response to lead ion

Water-soluble CdTe quantum dots (QDs) have been utilized as photoluminescence probes for the detection of metal ions such as Pb2+, Hg2+ , Cd2+ , etc. We initially developed highly photoluminescence (PL) Zn-doped CdTe for toxic ions detection.
