Figure 3. Effect of improper calibration of the Raman shift axis on peak locations.

Figure 3.

Raman spectra were acquired from silicon using an 830 nm laser source before (red) and after (black) calibration (B). When a commercial research-grade RS instrument is not properly calibrated, the wavenumber location of peaks such as ν1PO4 (inset) are shifted from their known location (B).
