Optical properties of poly-vinyl pyrrolidone encapsulated PbS/CdS coreshell quantum dots
PbS/CdS core-shell quantum dots have been synthesized through chemical route. PbS shows polycrystalline cubic structure and CdS shows hexagonal structure. The photoluminescence study shows a blue shift of near band gap emission of core PbS when coated with shell CdS. PbS shows a band gap of 2.2 eV a...
