В диапазоне температур 6—300 К установлены механизмы излучательной рекомбинации неравновесных носителей заряда, определяющие появление широких полос ФЛ в области энергий 0.7—1.1 эВ. Для прямозонного соединения Cu2ZnSnSe4 p-типа проводимости обнаружен эффект перераспределения интенсивности между каналами излучательной рекомбинации в спектральной области 0.93—0.99 эВ, указывающий на наличие глубоких акцепторных и донорных уровней в запрещенной зоне. По данным тушения интенсивности широких полос ФЛ в области энергий 0.7—1.0 эВ определена термическая энергия активации каналов безызлучательной рекомбинации с участием дефектов структуры, обсуждается их природа.</p></abstract><trans-abstract xml:lang="en"><p>   Based on the photoluminescence (PL) and PL excitation spectra of the Cu2ZnSnSe4 thin film compound with the kesterite structure the optical width of the direct band gap was determined to be Eg ≈ 1.052 eV at the temperature of 6 K. In the temperature range of 6–300 K the mechanisms of radiative recombination of nonequilibrium charge carriers were established. These mechanisms determine the appearance of wide PL bands in the energy region of 0.7–1.1 eV. For the direct-gap compound Cu2ZnSnSe4 with p-type conductivity the effect of redistribution of the intensity between radiative recombination channels in the spectral region of 0.93–0.99 eV was detected, indicating the presence of deep acceptor and donor levels in the band gap. Based on the data on the intensity quenching of broad PL bands in the energy range of 0.7—1.0 eV the thermal activation energy of nonradiative recombination channels involving structural defects was determined andtheir nature was discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Cu2ZnSnSe4</kwd><kwd>тонкая пленка</kwd><kwd>фотолюминесценция</kwd><kwd>дефект структуры</kwd><kwd>ширина запрещенной зоны</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Cu2ZnSnSe4</kwd><kwd>thin film</kwd><kwd>photoluminescence</kwd><kwd>structural defect</kwd><kwd>band gap</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках проекта Белорусского республиканского фонда фундаментальных исследований № Ф24–010 и проекта Министерства науки и высшего образования РФ (“Спин” № 122021000036-3)</funding-statement><funding-statement xml:lang="en">The work was carried out as part of the project of the Belarusian Republican Fund for Fundamental Research No. F24–010 and the project of the Ministry of Science and Higher Education of the Russian Federation (“Spin” No. 122021000036-3)</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.
