摘要: 利用紫外光电子能谱(UPS)对在Ag(110)表面上荧光素(fluorescein)的生长进行研究. 研究表明, 与fluorescein分子轨道有关的4个特征峰分别位于费米能级以下2.70, 3.80, 7.40和9.80 eV处. 角分辨紫外光电子能谱(ARUPS)测量结果表明, fluorescein分子的三苯环平面平行衬底平面, 分子的C=O轨道轴向接近于[1-10]晶向.

Abstract: The thin films of fluorescein grown on Ag(110) have been studied by the ultraviolet photoemission spectroscopy(UPS). Four emission features are located at 2.70, 3.80, 7.40, and 9.80 eV below the Fermi level, respectively. The angle-resolved ultraviolet photoemission spectroscopy(ARUPS) suggests that the triring plane of fluorescein is parallel to the substrate and the axis of the C=O orbit is close to the [1-10] azimuth.
