Toward a Facile One-Step Construction of Quantum Dots Containing Zn₈S Cores

Abstract

Three neutral nanoclusters Zn8S(SC6H5)14L2 [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
