Advantages
Broad Application: Suitable for plastics, rubber, paints, adhesives, foods, batteries, and more.
Luminescent Properties: Used in LCDs, TFTs, and LEDs.
UV Protection: Provides broad-spectrum UVA and UVB absorption.
Theory
Zinc oxide is an N-type semiconductor with excellent luminescent properties at room temperature. Its large energy band gap and exciton binding energy result in high transparency. UV absorption occurs when valence band electrons absorb UV energy and transition. Scattering efficiency depends on particle size, with nanoscale particles offering superior performance.
