The Sum Decomposition Method for the Gaussian Functions Comprising the Experimental Photoluminescence Spectrum
Abstract
We propose a method of the sum decomposition for Gaussian functions which allows expanding of the experimental photoluminescence spectrum into individual Gaussian emission bands. The decomposition process is carried out on the basis of a single experimental measurement. Meanwhile, the calculation of the Gaussian parameters (amplitude, maximum location, and half-width of the spectrum) is performed using three experimental points. The method was tested in the analysis of the photoluminescence spectra of ZnS:Mn crystals where individual emission bands were revealed by the proposed method as well as by the Alentsev-Fock and derivative spectroscopy methods.
