LARGE-SCALE SYNTHESIS AND PHOTOLUMINESCENCE OF ZnS HIERARCHICAL NANOSTRUCTURES ON SILICA GLASS SUBSTRATE

A novel hierarchical structured ZnS microsphere comprised of nanosheets on the silica glass substrate has been prepared on a large scale by a simple hydrothermal synthesis route. As an important II-VI semiconductor, large-scale hierarchical ZnS nanostructure has not been easily fabricated on silica glass substrate. Here, we confirm the formation of this hierarchical nanostructure by XRD, EDS and FESEM. Moreover, the photoluminescence (PL) properties of the ZnS films have been studied in terms of PL emission spectroscopy. Additionally, the effect of hydrothermal reaction temperature on the formation of ZnS film was investigated in this paper. The possible growth mechanism for the formation of this novel hierarchical ZnS microsphere was also proposed based on the FESEM observations.
