Процесс разложения осуществляется на основе одного экспериментального измерения, при этом расчет параметров гауссиана (амплитуды, положения максимума и полуширины спектра) проводится по трем экспериментальным точкам. Метод апробирован при анализе спектров фотолюминесценции кристаллов ZnS:Mn, в которых индивидуальные полосы выявлялись предложенным методом, а также методами Аленцева—Фока и производной спектроскопии.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фотолюминесценция</kwd><kwd>кристалл сульфида цинка</kwd><kwd>индивидуальные полосы излучения</kwd><kwd>метод декомпозиции гауссовых функций</kwd><kwd>метод производной спектроскопии</kwd><kwd>метод Ален-цева—Фока.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photoluminescence</kwd><kwd>zinc sulfide crystals</kwd><kwd>individual emission bands</kwd><kwd>decomposition method of Gaussian functions</kwd><kwd>derivative spectroscopy method</kwd><kwd>Alentsev-Fock method</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Z.
