摘要： 利用X光电子能谱（XPS）和高分辨电子能量损失谱（HREELS）研究了几种条件下LiF和Al的化学反应.在有Alq3参与的情况下,LiF和Al在室温下发生反应.在Al/LiF/Alq3系统中,Li 1s的峰发生了0.25 eV的位移,同时F 1s也发生了相应的位移.在没有Alq3参与的情况下,加热样品至350 K后,在Li 1s峰的低能端0.85 eV处出现了一个伴峰.XPS研究表明,这个伴峰对应的是金属态的Li 1s.HREELS的结果也验证了这一结论.

Abstract: The interaction between LiF and Al has been studied by X-ray photoemission spectroscopy (XPS) and high-resolution electron energy loss spectroscopy (HREELS).The reaction between LiF and Al occurs in the presence of Alq3 at room temperature. In the Al/LiF/Alq3 system, the Li 1s peak shifts 0.25 eV relative to the F 1s peak during the reaction. On warming the Al substrate covered LiF to 350 K, interaction between LiF and Al is revealed by a shoulder peak, which is about 0.85 eV below the original Li 1s peak. XPS measurement revealed that the shoulder peak corresponds to metal Li 1s, this result is confirmed by HREELS measurements.
