Stable in monotonous air, it gradually oxidizes to zinc sulfate when left in humid air or containing moisture for a long time. Soluble in dilute inorganic acids, soluble in alkalis, insoluble in water. Relative density 3.98( α Type), (d25) 4.102( β Type). Irritating.

As an important two or six compound semiconductor, zinc sulfide nanomaterials have attracted great attention not only due to their excellent physical properties such as wide bandgap, high refractive index, and high transmittance in the visible light range, but also due to their enormous potential in the application of optical, electronic, and optoelectronic devices. Zinc sulfide has excellent fluorescence effect and electroluminescence function, and nano zinc sulfide has a combined photoelectric effect, showing many excellent functions in fields such as electricity, magnetism, optics, mechanics, and catalysis. Therefore, the research on nano zinc sulfide has attracted more attention, especially in 1994 when Bhargava reported that surface passivation treated nano ZnS: Mn phosphors have an external quantum efficiency of up to 18% at high temperatures, Its fluorescence lifetime has been shortened by 5 orders of magnitude, and its luminescence function has undergone significant changes, opening up a new way for the application of ZnS in information technology. Can be used to make white pigments and glass, luminescent powder, rubber, plastic, luminescent paint, etc.
