The reaction between MgF2 and tris (8-hydroxy-quinoline) aluminum (Alq(3)) has been studied using high-resolution electron-energy-loss spectroscopy (HREELS). The reaction between MgF2 and Alq(3) occurs in the cases of MgF2 deposited on Alq(3) and Alq(3) on MgF2. The shift of the loss peak corresponding to the out-of-plane ring bend is observed to be similar to that for Mg deposited on Alq(3). The HREELS spectra indicate that Mg is produced from MgF2 deposited on Alq(3), and interacts with Al, O and N in Alq(3). Analysis of the HREELS results suggests that Mg is not in the Alq(3) molecule plane.
