По полученным спектрам определена ширина запрещенной зоны указанных соединений и твердых растворов на их основе, а также построены ее концентрационные зависимости. Показано, что ширина запрещенной зоны с параметром состава x при 295 K изменяется нелинейно и описывается квадратичной зависимостью.</p></abstract><trans-abstract xml:lang="en"><p>Single crystals of In2S3, FeIn2S4 compounds and their solid solutions (FeIn2S4)1- x  (In2S3)x have been grown by directional crystallization of the melt (vertical Bridgman method). Transmission spectra of the grown crystals in the intrinsic absorption edge region were investigated. Band gap width ( Eg ) and its concentration dependence have been determined on the measured spectra. It is established, that band gap width Eg changes nonlinearly with composition x .</p></trans-abstract><kwd-group xml:lang="ru"><kwd>монокристалл</kwd><kwd>спектр пропускания</kwd><kwd>ширина запрещенной зоны</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">Боднарь И.В., Федотова Ю.А., Новикова М.А. // Неорганические материалы. 2011.
