Исследовано влияние легирования азотом на структурные и оптические свойства люминофоров ZGO. Показано, что ионы азота успешно заменяют ионы кислорода и легирование азота распространяется по всей элементарной ячейке кристаллической решетки. Небольшое синее смещение энергии запрещенной зоны указывает на слабое квантовое удержание полученных наночастиц ZGO. При длине волны возбуждения 260 нм по сравнению со спектром фотолюминесценции люминофоров ZGO положение максимума излучения люминофоров ZGO, легированных азотом, смещается в синюю область. В колебательных режимах ZGO из-за включения азота водород замещается в O-сайте, что вызывает пассивацию в наночастицах ZGO:N. Концентрация ионов азота в ZGO:N играет важную роль в эволюции интенсивности фотолюминесценции и качества нанокристаллов. Результат способствует оптимизации легированных азотом люминофоров с содержанием 5 мол.%. Обсуждается возможный механизм люминесценции люминофоров ZGO:N.</p></abstract><trans-abstract xml:lang="en"><p>Nitrogen-doped Zn2GeO4 (ZGO:N) phosphors were synthesized using a chemical hydrothermal approach. The influence of nitrogen doping on the structural and optical properties of ZGO phosphors was investigated. Results indicated that N ions substituted for O ions successfully and N doping expanded throughout the unit cell of the crystal host lattice. We observed a slight blue-shift in bandgap energy, which signified the weak quantum confinement of the prepared ZGO nanoparticles. At a 260-nm excitation wavelength, compared with the photoluminescence (PL) spectrum of the ZGO phosphors, the peak position of emission  of the N-doped ZGO phosphors blue shifted. In the vibrational modes of ZGO owing to N incorporation,  H substituted at the O site, subsequently causing passivation in ZGO:N nanoparticles. The concentration  of N ions in ZGO:N played important roles in the evolution of PL intensity and quality of nanocrystals. This result contributed to the optimization of nitrogen-doped phosphors with 5 mol% content. The possible luminescence mechanism of ZGO:N phosphors was also discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>люминофоры Zn2GeO4</kwd><kwd>легирование азотом</kwd><kwd>гидротермальный метод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Zn2GeO4 phosphors</kwd><kwd>nitrogen-doped</kwd><kwd>hydrothermal method</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">This research was funded by the Hanoi University of Science and Technology (HUST) under project number T2020-SAHEP-032.</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">L.
