Toward a facile one-step construction of quantum dots containing Zn8S cores.
Three neutral nanoclusters Zn 8S(SC 6H 5) 14L 2 [L = 3-aminopyridine ( 1), 4-(dimethylamino)pyridine ( 2), 4-methylpyridine ( 3)] featuring a wurtzite-like core have been assembled by a controlled one-step hydrothermal reaction. Their detailed photoluminescence properties depend upon the ligand substituents. Cluster 1 exhibited a narrow, symmetric emission spectrum and has a potential application as a fluorescence quantum dot.
