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.
