Absorption Coefficient of NaF by Attenuated Total Reflection Spectroscopy

Source

Attenuated total reflection (ATR) spectroscopy has been employed to measure the absorption coefficient of NaF films from the visible to 3 µm. A 1-mm-thick ZnSe ATR plate (50-mm long) was coated on two sides with NaF (0.55- and 0.57-µm-thick films). By coating half the width of the ATR plate, “sample-in/sample-out” measurements could be performed to reduce substrate effects. The spectra reveal a strong water band in NaF peaking at 2.95 µm with a peak absorption coefficient at 165 cm-1 relative to the substrate. Scattering effects are noted at shorter wavelengths, and it is estimated that 7 Å of water are adsorbed onto the bare ATR plate.
