Synthesis, structural and optical properties of ZnS
ZnS is a semiconductor nanomaterial of direct and wide-bandgap. It is usually observed in two phases, cubic and hexagonal. The hexagonal phase has a wurtzite structure while the cubic phase has a zinc blende structure. For the cubic and hexagonal phases of ZnS, the bandgap energy is 3.68 eV and 3.80 eV, respectively.

Zinc Sulfide
ZnS is a group of II–VI wide band gap semiconductor materials with a band gap, which range between 3.6-3.8 eV. The ZnS has two types crystal structures namely zinc blende and wurtzite. Among the two, zinc blende also referred to as β‐ZnS is stable at low temperature, whereas wurtzite, also referred to as α-ZnS is stable at temperature >1024°C.

Abstract. The urgent need for highly safe and sustainable large-scale energy storage systems for residential buildings has led to research into aqueous zinc ion batteries. However, when zinc is used in aqueous zinc ion batteries, it suffers from severe irreversibility due to its low Coulombic efficiency, dendrite growth, and side reactions.
