Zinc oxide is an inorganic substance with the chemical formula ZnO, which is an oxide of zinc. Difficult to dissolve in water, soluble in acids and strong bases. Zinc oxide is a commonly used chemical additive, widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paint coatings, ointments, adhesives, food, batteries, flame retardants, and other products. Zinc oxide has a large bandgap and exciton binding energy, high transparency, and excellent room temperature luminescence performance. It is widely used in products such as liquid crystal displays, thin film transistors, and light-emitting diodes in the semiconductor field. In addition, microparticle zinc oxide as a nanomaterial has also begun to play a role in related fields.
