По данным рентгеноструктурного анализа определены параметры элементарной ячейки a ~ 5.720 Å, c ~ 11.52 Å и элементный состав х = Ga/(Ga+In) ~ 0.14 и у = S/(S+Se) ~ 0.11 тонких пленок Cu(In1–хGaх)(SуSe1–у)2 . Из спектров фотолюминесценции и возбуждения люминесценции при температуре ~4.2 К определена оптическая ширина запрещенной зоны твердых растворов Cu(In1–хGaх)(SуSe1–у)2 Eg ~ 1.122 эВ.

According to the data of X-ray diffraction analysis the unit cell parameters were a ~ 5.720 Å and c ~ 11.52 Å, and the elemental compositions were x = Ga/(Ga+ In) ~ 0.14 and y = S/(S + Se) ~ 0.11 for Cu(In1–xGax)(SуSe1-y)2 thin films. Optical band gap of Cu(In1–xGax)(SуSe1-y)2 solid solutions was determined from the measurements of photoluminescence spectra and luminescence excitation spectra at a temperature of ~4.2 K and appeared to be equal ~ 1.122 eV. Mechanism of radiative recombination of nonequilibrium charge carriers in thin films of Cu(In1–xGax)(SуSe1-y)2 solid solutions is discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>твердые растворы Cu(In1–хGaх)(SуSe1–у)2</kwd><kwd>тонкая пленка</kwd><kwd>фотолюминесценция</kwd><kwd>оптическая ширина запрещенной зоны</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Cu(In1–xGax)(SySe1–y)2solid solutions</kwd><kwd>thin film</kwd><kwd>photoluminescence</kwd><kwd>optical band gap</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена по проекту Белорусского республиканского фонда фундаментальных исследований Ф20М-058, программе ГПНИ “Физическое материаловедение, новые материалы и технологии” (подпрограмма “Наноматериалы и нанотехнологии”-2.56) и государственного задания Министерства образования и науки РФ (“Спин” № АААА-А18-118020290104-2).</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">M.
