ELECTRON GRADE ZINC OXIDE

NANO-ZINC OXIDE FOR FLUORESCENCE PRODUCTS

Nano Zinc oxide for Fluorescent products
   Zinc oxide is a low-voltage electron beam of light-emitting material can be the only, light blue and red colors, the energy gap is 3.2eV, corresponding to the UV wavelength 387nm. When the nano-Zinc oxide particles by ultra-violet light, the particles of the photo-generated electrons and holes will quickly spread to the surface, in the face of complex photochemical reactions, while zinc oxide particles also have a series of reactions fluorescence occurred, using the properties of Zinc oxide fluorescent products can be prepared.
