Below are the most common models that researchers use to analyze cathodoluminescence spectra.
The Least-Square Fitting tool supports multiple models for NLLS fitting that can be combined into a single fit. This section describes the various models in detail.
Gaussian
Peak-function is characterized by a maximum position and intensity as well as the peak-width measured as the full width at half-maximum.
Non-Negative Gaussian – Limits the amplitude to positive values.
Lorentzian
Peak-function characterized by a maximum position and intensity and the peak- width measured as the full width at half-maximum.
