В работе представлены результаты исследования оптических свойств и механизмов роста двумерных нанопластин кадмий селенида (CdSe), полученных методом коллоидного синтеза. Установлены зависимости спектров фотолюминесценции от температуры и инжекции прекурсоров, показано, что увеличение толщины нанопластин сопровождается сдвигом излучения в длинноволновую область. Исследованы концентрационные условия роста, продемонстрирована возможность управления числом монослоёв в структурах CdSe за счёт изменения температуры и введения дополнительных количеств исходных веществ. Проведён элементный анализ полученных нанопластин, подтверждающий их химическую однородность. Полученные результаты позволяют глубже понять процессы формирования двумерных наноструктур CdSe и могут быть использованы для оптимизации их оптоэлектронных характеристик.

Modern studies demonstrate that two-dimensional nanomaterials hold great promise for various practical applications. At present, 2D materials are being actively investigated through colloidal synthesis in specialized formats, enabling the creation of materials with precisely defined structures and the enhancement of their functional properties. CdSe nanoplatelets (NPLs) exhibit high efficiency in light absorption and photoluminescence, making them suitable for applications in solar cells and optical devices. The synthesis of quantum-confined CdSe NPLs is carried out in colloidal solvents. The dependence of NPL photoluminescence on temperature and precursor injection has been studied. It has been established that with an increase in NPL thickness, their photoluminescence spectra shift to the longer wavelength region as the temperature rises. The study presents the dependence of precursor concentration in the reaction medium and the growth mechanism of NPLs. Additionally, the work explores the specifics of colloidal synthesis of CdSe NPLs, provides a detailed characterization of their properties, and substantiates the theory of nanostructure growth.
