Figure 6
XPS spectra of the oxygen O 1s core level. (1) Sample #1, (2) sample #1 irradiated at 10 kGy, (3) sample #1 irradiated at 500 kGy. Scatter represents experimental data whereas solid lines are best fitting (using Al Kα source hν = 1486.6 eV). The fitted high-energy peak is due to BO and the low-energy peak is due to NBO. |
