Porous ZnS precursors were prepared by soft template method and Soxhlet extraction method. We used three surfactants with different molecular weight, which included ODA, Pluronic P123, and Pluronic F127, as soft template agents. Nitrogen adsorption-desorption results indicated that larger molecular weight and larger amounts of the template agent made porous ZnS precursors with larger pore sizes and smaller specific surface areas. The final ZnS fluorescent samples were obtained through calcinations method in tube furnace. The emission peaks of ZnS porous fluorescent samples were approximately 490 nm because of zinc vacancy, which was similar to ZnS nanoparticles. However, the emission intensity of porous ZnS fluorescent samples was 2.3-fold greater than that of ZnS nanoparticles, because that the porous cavity can increase the utilization ratio of excitation light and cause more absorption of excitation light, improve the luminescent properties of ZnS phosphor.

“…Intrinsic and visible emissions in ZnS NPs have been well-reported [30][31][32], and their PL properties have been explored by many researchers [9,25,[33][34][35][36], while the photocatalytic properties of ZnS NPs have been analyzed by many authors for a variety of reactions [27][28][29][37][38][39][40][41][42], however, the photocatalytic and PL behavior at nanoscale sizes remain far from well-understood.…”

From the viewpoints of materials chemistry and physical chemistry, crystal structure directly determines the electronic structure and furthermore their optical and photocatalytic properties. Zinc sulfide (ZnS) nanoparticles (NPs) with tunable photoluminescence (PL) emission and high photocatalytic activity have been obtained by means of a microwave-assisted solvothermal (MAS) method using different precursors (i.e., zinc nitrate (ZN), zinc chloride (ZC), or zinc acetate (ZA)). The morphologies, optical properties, and electronic structures of the as-synthesized ZnS NPs were characterized by X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDX), Brunauer-Emmett-Teller (BET) isotherms for N 2 adsorption/desorption processes, diffuse reflectance spectroscopy (DRS), PL measurements and theoretical calculations. Density functional theory calculations were used to determine the geometries and electronic properties of bulk wurtzite (WZ) ZnS NPs and their (0001), (101 ̅0), (112 ̅0), (101 ̅1), and (101 ̅2) surfaces. The dependence of the PL emission behavior of ZnS NPs on the precursor was elucidated by examining the energy band structure and density of states. The method for degradation of Rhodamine B (RhB) was used as a probe reaction to investigate the photocatalytic activity of the as-Synthesised ZnS NPs under UV light irradiation. The PL behavior as well as photocatalytic activities of ZnS NPs were attributed to specific features of the structural and electronic structures. Increased photocatalytic degradation was observed for samples synthesized using different precursors in the following order: ZA < ZC < ZN. These results indicated that samples synthesized with ZN present a greater percentage of exposed (0001) surface than those synthesized with the ZC and ZA. Furthermore, the possible photodegradation mechanism of the as-prepared ZnS NPs were also briefly discussed.
