“…Therefore, ZnS is a traditional phosphor widely used in flat-panel display, electroluminescent devices, infrared windows, sensors, and lasers. − Doped ZnS with selected metal ions is a promising material in mechano-optic applications . The photoluminescence of Cu, Co, Eu, Ce, and Er doped ZnS nanomaterials has also been investigated. − In general, the spherically monodisperse morphology is an important factor for the low-light scattering at the surfaces, as well as the high-packing densities …”
