| Abstract |
The 20-MeV proton-beams with a fluence of 10¹² cm⁻² were irradiated on ZnO nanorods. The effects of proton-beam irradiation on ZnO nanorods are investigated by using ¹H nuclear magnetic resonance (NMR) spectroscopy. After irradiation, new and modified NMR resonance lines are observed in ¹H NMR spectra. The diffusion and thermal stability of each proton species are investigated from the lab- and rotating-frame spin-lattice relaxation data depending on temperature. Understanding the properties of thermally stable hydrogen species created by the beam irradiation may promise many possible applications, since the hydrogen stable up to high temperature only meets the device working conditions.
