Полученные частицы обладают кристаллической структурой цинковой обманки с размером кристаллита 3.8 нм. Исследованы морфологии и оптические характеристики синтезированных частиц. Обнаружено, что ширина запрещенной зоны изменяется от 3.6 до 4.4 эВ в зависимости от концентрации меди. Исследована фотолюминесценция частиц при комнатной температуре.</p></abstract><trans-abstract xml:lang="en"><p>Copper doped zinc sulfide nanoparticles have been synthesized using a wet chemical method. The synthesized nanoparticles exhibit a zinc blende structure with the crystallite size of 3.8 nm. The morphological and optical studies of the synthesized nanoparticles have been performed. It is found that the band gap varies from 3.6 to 4.4 eV depending upon the concentration of copper. The room temperature photoluminescence of the synthesized nanoparticles has been also investigated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ZnS</kwd><kwd>ZnS:Cu</kwd><kwd>рентгеноструктурный анализ</kwd><kwd>сканирующая электронная микроскопия</kwd><kwd>просвечивающая электронная микроскопия</kwd><kwd>наночастица</kwd><kwd>фотолюминесценция</kwd><kwd>ZnS</kwd><kwd>ZnS:Cu</kwd><kwd>X-ray diffractometry</kwd><kwd>scanning electron microscopy</kwd><kwd>transmission electron microscopy</kwd><kwd>nanoparticles</kwd><kwd>photoluminescence</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">M.
