| Abstract
| - Phosphatidylcholine vesicles provide reaction compartments for the synthesis of nanometer-size CdS,ZnyCd1-yS, and HgyCd1-yS particles with size- and composition-tunable absorbance and luminescencefeatures. Spectrophotometric and spectrofluorimetric measurements are consistent with crystalline,monodisperse particles with few core or surface defects and uniform core composition. Core−shell CdS−HgS and CdS−ZnS nanocrystals also are synthesized within the vesicle interiors by alternating additionof cations and sulfide to build layered particles. These materials exhibit well-defined, yet qualitativelydifferent, absorbance and luminescence spectra and establish the versatility of vesicles for synthesis ofboth mixed and layered composition nanocrystals.
