Theory

Zinc oxide belongs to the N-type semiconductor category, exhibiting excellent luminescent properties at room temperature. It has a large energy band gap and exciton binding energy, resulting in high transparency. The principle of zinc oxide absorbing UV radiation is that electrons in the valence band can absorb energy from UV radiation and undergo transitions. The function of scattering UV radiation is related to the particle size of the material, with nanoscale particles offering significant advantages.
