Оптические постоянные измерены эллипсометрическим методом Битти в диапазоне 0.248—7.002 мкм. Из спектральных зависимостей оптических постоянных рассчитаны дисперсионные зависимости световой проводимости σ, отражательной способности R, мнимой и действительной частей диэлектрической проницаемости ε1 и ε2, функции характеристических потерь энергии электронов Im(ε)–1. Показано влияние кристаллической структуры сплавов на особенности их оптических спектров. На основе результатов измерений в инфракрасной области спектра по модели двухполосной проводимости рассчитаны электронные характеристики указанных сплавов. </p></abstract><trans-abstract xml:lang="en"><p>The optical properties and electronic characteristics of X-ray amorphous and polycrystalline Al4Sm alloy films obtained by vacuum thermal evaporation were studied. The optical constants were measured by the Beattie ellipsometric method in the range of 0.248–7.002 µm. From the spectral dependencies of optical constants, the dispersion dependences of the light conductivity σ, reflectivity R, imaginary and real parts of the dielectric permittivity ε1 and ε2 and functions of characteristic energy loss of electrons Im(ε)–1 were calculated. The effect of the crystal structure of the alloys on the features of their optical spectra was shown. Based on the results of measurements in the infrared region of the spectrum, the electronic characteristics of these alloys were calculated using the two-band conductivity model. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>эллипсометрия</kwd><kwd>оптические свойства поликристаллических и аморфных сплавов</kwd><kwd>характеристики электронов проводимости</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ellipsometry</kwd><kwd>optical properties of polycrystalline and amorphous alloys</kwd><kwd>characteristics of conduction electrons</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в соответствии с государственным заданием Института химии твердого тела УрО РАН № АААА-А19-119031890028-0.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Y.
