Raman Spectra of Nanodiamonds: New Treatment Procedure Directed for Improved Raman Signal Marker Detection

Figure 7

This plot shows the calculated bell-like curves and their fit to the beta-distribution function (12). The fitting parameters are collected in Table 2. One can notice that the behavior of these curves with respect to the values of the annealing temperatures is not monotone. The highest curve belongs to the annealing spectrum with 475°C. Then the curves belonging to RS before annealing and 425°C have monotone behavior and the lowest curve belongs to the annealing temperature 575°C.
