Zinc sulfide is a chemical compound. It is typically encountered in the more stable cubic form, known also as zinc blende or sphalerite.
ZnS was used by Ernest Rutherford and others in the early years of nuclear physics as a scintillation detector, because it emits light on excitation by x-rays or electron beam, making it useful for x-ray screens and cathode ray tubes. It also exhibits phosphorescence due to impurities on illumination with blue or ultraviolet light.
