Установлено, что монокристаллы кристаллизуются в кубической структуре шпинели с постоянной решетки a = 10.765 ± 0.005 Å. По спектрам пропускания в области края собственного поглощения в интервале температур 10—320 К оценена ширина запрещенной зоны монокристаллов Mn1.5AgIn8.0S14, установлено ее уменьшение с ростом температуры и найдена функциональная аппроксимация этой зависимости.</p></abstract><trans-abstract xml:lang="en"><p>Mn1.5AgIn8.0S14 single crystals were grown by the Bridgman directed melt crystallization method. Crystals composition and structure were determined. It was found that these single crystals crystallize in a cubic spinel structure with a lattice constant a = 10.765 ± 0.005 Å. The width of the band gap of Mn1.5AgIn8.0S14 single crystals was estimated from the transmission spectra in the region of the edge of its intrinsic absorption in the temperature range of 10—320 K. The band gap width decreases with the temperature increasing and a functional approximation of this dependence was obtained.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метод Бриджмена</kwd><kwd>кристаллическая структура</kwd><kwd>спектр пропускания</kwd><kwd>коэффициент поглощения</kwd><kwd>ширина запрещенной зоны</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Bridgman method</kwd><kwd>crystal structure</kwd><kwd>transmission spectra</kwd><kwd>absorption coefficient</kwd><kwd>band gap</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">Р.
