| Abstract: | A facile route to synthesis high-quality CdTe nanocrystals with strong luminescence was designed in aqueous solution using an electrogenerated H2Te as Te source,which is easy to control,safety,cost-efficiency and large-scale.Base on this synthetic route,we systematically investigated the influence of various experimental factors on the synthesis of CdTe nanocrystals,such as the pH,the ratio between ligand and Cd2+.Under optimal experimental conditions,the quantum yield of theses as-prepared MPA-capped CdTe ... |
