| 中文摘要 | colloidal cdse/cds nanocrystals are synthesized at low temperatures (40-70 degrees c) via a two-phase approach at an environmentally friendly n-heptane-water interface. oil-soluble cadmium myristate (cd-ma) is used as cadmium source, while thiourea and selenourea are used as sulfur and selenium sources, respectively. first, the cdse nanocrystals are achieved at an n-heptane-water interface with a diameter ranging from 1.77 to 1.83 nm at 40 degrees c. subsequently, highly luminescent cdse/cds core-shell nanocrystals are synthesized using poorly reactive thiourea as sulfur source at 70 degrees c in a two-phase system. as-prepared core-shell nanocrystals have a quantum yield (pl qy) of up to 73% relative to coumarin 6 at room temperature. meanwhile, the influence of cdse core size and cds shell thickness on pl qy and pl lifetime are also investigated. |
