To accomplish the fitting, relative peak positions were fixed by the spectroscopic model chosen, the peak widths were fixed as determined in the previous discussion and the heights of the photoelectron peaks were allowed to vary in order to minimize the fitting errors with the least squares technique.
When the spectra of the quantum efficiencies are considered with transmission spectra it is found that 66.5% and 62.9% of the produced photons contribute the production of photoelectron in APD and PIN diode, respectively.
Finally, the recorded infrared spectra, photoelectron, and Auger electron spectra may be found to be of great importance in the future for an accurate IR and XPS evaluation of zinc corrosion products formed in NaCl environment on the surface of ternary zinc alloy coatings containing molybdenum, and for further investigation of the corrosion mechanism thereof.
