Optical properties of ZnS nanosheets, ZnO dendrites, and their lamellar precursor ZnS·(NH2CH2CH2NH2)0.5

The optical properties of 2D wurtzite ZnS nanosheets, ZnO dendrites, and their lamellar precursor ZnS·(NH2CH2CH2NH2)0.5 were investigated. The lamellar precursor ZnS·(NH2CH2CH2NH2)0.5 with highly confined quantum dots effect was produced by a mild solvothermal reaction using Zn(CH3COO)2·2H2O or ZnCl2 with thiourea or sulfur in ethylenediamine at 120–180 °C. The following decomposition and oxidization of the precursor produced 2D ZnS nanosheets and ZnO dendrites, respectively. The 2D sheet-like ZnS·(NH2CH2CH2NH2)0.5 with highly confined quantum dots effect and ZnS nanosheets could find applications in electronic nanodevices or biotechnology.
