Optical radiation stability of ZnO hollow particles

Статья в журнале

Zinc oxide has multifunctional physical properties depending on its microstructure and morphology. Herein, we reported the in situ investigations of the radiation stability of ZnO particles with hollow, ball, star and flower shapes under electron and proton irradiation. 100 keV protons with a fluence of 5 × 1015 cm-2 and 50 keV electrons with fluence ranging from 0.5 to 7 × 1016 cm-2 are employed to investigate the radiation stability of nanostructured ZnO particles. In situ reflectance, X-ray photoelectron spectra and photoluminescence were characterized in the irradiation environment to avoid the effects of the atmospheric environment on radiation induced defects. The experimental results reveal that, compared to the other shapes, the hollow structure with the best radiation stability due to the hollow structure facilitates the decrease of the accumulation of radiation defects. This study clearly demonstrates the promise of ZnO hollow particles as a plasmonic nanostructure for achieving high radiation stability, and they could be easily employed to serve as the radiation stability pigment for coatings.
