Abstract
The rotating-frame spin-lattice relaxation of two types of the hydrogen donors was well distinguished in the 1H nuclear magnetic resonance measurements in a sol-gel prepared ZnO system, providing a unique opportunity to study the distinct proton dynamics. Our study indicates interconversion of the interstitial H (Hi). The population of the mobile Hi showed decrease above ∼370 K, apparently being trapping into the oxygen vacancies resulting in the more stable oxygen-substitutional H (H O). The activation barrier for migration of Hi and the binding energy of H O were found to be 0.27 eV and 0.51 eV, respectively.
