This paper reports a modified version of hot injection method for the synthesis of CdSe quantum dots and CdSe–ZnSe nano–tetrapod structures. In the present method, certain synthesis parameters such as injection temperature, growth temperature and precursor ratio were tuned to influence the growth kinetics and thereby the optical properties of the prepared CdSe QDs were enhanced. The influences of these parameters were studied and suitable conditions were optimized. Using the optimized parameters, CdSe–ZnSe nanostructures were synthesized with tetrapod morphology and their structural and optical properties were studied. The adopted modified version of synthesis is a facile method without stringent conditions such as inert atmosphere and therefore adaptable for the large-scale synthesis in industry. 

В статье описан модифицированный вариант метода горячего впрыска для синтеза квантовых точек CdSe и нанотетраподных структур CdSe–ZnSe. В настоящем варианте реализации метода были оптимизированы определенные параметры синтеза, такие как температура впрыска, температура роста и соотношение прекурсоров, и настроены так, чтобы влиять на кинетику роста, и тем самым оптические свойства приготовленных квантовых точек CdSe. С использованием оптимизированных параметров синтезированы наноструктуры CdSe – ZnSe с тетраподной морфологией и изучены их структурные и оптические свойства. Принятая модифицированная версия синтеза представляет собой простой метод без жестких условий, таких как инертная атмосфера, и поэтому пригодна для крупномасштабного синтеза в промышленности.
