对氧化锌中氢施主的拉曼光谱研究揭示了键心氢()和氧空位中的氢()的性质。施主的电子跃迁和特征的局域振动模式是确定施主的依据。施主优先在样品表面以下检测到，样品的热处理产生了较高的氧空位浓度，并且具有不同的热稳定性，它们的浓度强烈地依赖于样品的历史。分子氢是两个氢供体相互作用的重要组成部分。
A Raman study on hydrogen donors in ZnO reveals the properties of bond-centered hydrogen () and hydrogen trapped in the oxygen vacancy (). The donors are identified by their electronictransitions and their characteristic local vibrational modes. Thedonor was detected preferentially below the sample surface, where a high oxygen vacancy concentration is generated by thermal treatment of the samples.andexhibit different thermal stabilities and their concentrations depend strongly on the sample history. Molecular hydrogen is an essential part of the interplay of the two hydrogen donors.
