A way of colloidal ZnS QDs synthesis, different from knowing ways used for obtaining of these QDs (solvothermal and hydrothermal ways, solid state heating, ultrasonication) is proposed. It is similar to way for CdS synthesis, using oleates as metal precursor and trialkylphosphine sulfides as sulfur precursor. But instead of octadecene or diphenyl ether as solvents we used toluene. ZnS QDs with middle radius a = 1.77 nm, what corresponds to intermediate confinement regime (a ≈ aB, aB=2,5 nm is the excitonic Bohr radius for bulk ZnS) were obtained. |
