Abstract: A method is proposed for decomposing the integrated photoluminescence spectrum into components based on the analysis of an identifier, which is the ratio of the first and second derivatives of the experimental data. The question of the limits of applicability of this method of decomposition of a complex photoluminescence spectrum has been studied in this paper. The definition of the sensitivity of the method is given on the example of an integral spectrum formed by two Gaussians. The evolution of the dependence of the used identifier on the wavelength is shown with a change in the distance between the maxima of the elementary components. By means of a synthetic experiment, dependences of the sensitivity on the ratio of the half-widths and intensities of the components of the integral spectrum are plotted. The dependences obtained are non-linear and have local maxima and minima. The use of the calculated dependences makes it possible to estimate at what overlap of the bands the decomposition is still possible, and at what it is no longer possible to separate the elementary component from the integrated spectrum.
